This review focus on the phytochemical progress and biological studies of plants from the genus Balanophora (Balanophoraceae) over the past few decades, in which most plants growth in tropical and subtropical regions of Asia and Oceania, and nearly 20 species ranged in southwest China. These dioeciously parasitic plants are normally growing on the roots of the evergreen broadleaf trees, especially in the family of Leguminosae, Ericaceae, Urticaceae, and Fagaceae. The plants are mainly used for clearing away heat and toxic, neutralizing the effect of alcoholic drinks, and as a tonic for the treatment of hemorrhoids, stomachache and hemoptysis. And it has been used widely throughtout local area by Chinese people.
Cinnamic acid derivative tannins, possessing a phenylacrylic acid derivative (e. g. caffeoyl, coumaroyl, feruloyl or cinnamoyl), which connected to the C(1) position of a glucosyl unit by O-glycosidic bond, are the characteristic components in genus Balanophora. In addition, several galloyl, caffeoyl and hexahydroxydiphenoyl esters of dihydrochalcone glucosides are found in B. tobiracola, B. harlandii, and B. papuana. Other compounds like phenylpropanoids, flavonoids, terpenoids and sterols are also existed. And their biological activities, such as radical scavenging activities, HIV inhibiting effects, and hypoglycemic effects are highlighted in the review.
Several methods exist for the treatment of cancer in modern medicine. These include chemotherapy, radiotherapy, and surgery; most cancer chemotherapeutants severely affect the host normal cells. Hence the use of natural products now has been contemplated of exceptional value in the control of cancer. Plant-derived natural products such as flavonoids, terpenes, alkaloids, etc., have received considerable attention in recent years due to their diverse pharmacological properties including cytotoxic and cancer chemopreventive effects. Looking into this, the antioxidant and anticancer evaluation of Scindapsus officinalis (Roxb.) Schott fruits has been attempted to investigate its antitumor activity. The collection and authentication of the plant material mainly fruits and their various extractions was done. Identification of plant's active constituents by preliminary phytochemical screening was carried out. An in-vitro cytotoxic assay using the brine shrimp lethality assay with brine shrimp eggs (Artemia salina) at a dose of 1–10 μg/ml with the fruit extract was performed by the method described by Mayer et al. Cell viability using the Trypan blue dye exclusion test at a dose of 20, 40, 80, 120, and 160 μg/ml dissolved in DMSO (final concentration 0.1%), and cytotoxicity using the MTT assay where viable cells convert MTT into a formazan salt were performed. All pharmacological screening for acute toxicity and anti tumour studies using EAC 1 × 106 cells/mouse treated Swiss albino mice at a dose of 100 and 200 mg/kg/day orally was carried out. Biochemical and antioxidants predictions from various parameters like hematological, RBC, WBC count, PVC, total protein, Tissue Lipid Peroxidation, SOD, CATALASE, GPx, GST levels and anti tumour activity of Scindapsus officinalis were observed. The data was statistically analyzed by one-way ANOVA followed by Dunnett's and Tukey's multiple comparison test. The antitumor effect of the extract is evident from the increase in mean survival time (MST) lifespan, reduction in the solid tumor volume, and also the reversal of altered hematological parameters almost equal to normal. The methanolic extract (100–200 mg/kg/day orally) was found to be cytotoxic on human cancer cell lines. In addition, the methanolic extract had an antioxidant effect as reflected by a decrease in LPO, GST, and GPx (oxidant enzymes), and an increase in SOD and catalase.

Background and Aims
The holoparasitic flowering plant Balanophora displays extreme floral reduction and was previously found to have enormous rate acceleration in the nuclear 18S rDNA region. So far, it remains unclear whether non-ribosomal, protein-coding genes of Balanophora also evolve in an accelerated fashion and whether the genes with high substitution rates retain their functionality. To tackle these issues, six different genes were sequenced from two Balanophora species and their rate variation and expression patterns were examined.
Sequences including nuclear PI, euAP3, TM6, LFY and RPB2 and mitochondrial matR were determined from two Balanophora spp. and compared with selected hemiparasitic species of Santalales and autotrophic core eudicots. Gene expression was detected for the six protein-coding genes and the expression patterns of the three B-class genes (PI, AP3 and TM6) were further examined across different organs of B. laxiflora using RT-PCR.
Balanophora mitochondrial matR is highly accelerated in both nonsynonymous (dN) and synonymous (dS) substitution rates, whereas the rate variation of nuclear genes LFY, PI, euAP3, TM6 and RPB2 are less dramatic. Significant dS increases were detected in Balanophora PI, TM6, RPB2 and dN accelerations in euAP3. All of the protein-coding genes are expressed in inflorescences, indicative of their functionality. PI is restrictively expressed in tepals, synandria and floral bracts, whereas AP3 and TM6 are widely expressed in both male and female inflorescences.
Despite the observation that rates of sequence evolution are generally higher in Balanophora than in hemiparasitic species of Santalales and autotrophic core eudicots, the five nuclear protein-coding genes are functional and are evolving at a much slower rate than 18S rDNA. The mechanism or mechanisms responsible for rapid sequence evolution and concomitant rate acceleration for 18S rDNA and matR are currently not well understood and require further study in Balanophora and other holoparasites.

Tamarindus indica Linn. fruits (Chincha) are extensively used in culinary preparations in Indian civilization. Its vast medicinal uses are documented in Ayurvedic classics and it can be used singly or as a component of various formulations. Besides fruit, the Kasta (wood) of T. indica L. is also important and used to prepare Kshara (alkaline extract) an Ayurvedic dosage form. Pharmacognostical and physicochemical details of Chincha Kasta are not available in authentic literature including API (Ayurvedic Pharmacopoeia of India). The study is an attempt in this direction. T. indica L. stem with heartwood was selected and morphological, microscopic and physicochemical standardization characters along with TLC finger print, and fluorescence analysis were documented. Transverse section of stem showed important characters such as phelloderm, stone cells layer, fiber groups, calcium oxalate, crystal fibers, and tylosis in heartwood region. Four characteristic spots were observed under UV long wave, in thin layer chromatography with the solvent combination of toluene: ethyl acetate (8:2). The study can help correct identification and standardization of this plant material.

Plants of ethnomedicinal importance have contributed for the development of many new pharmacologically effective molecules/chemical entities to modern medicine. India, the country having one of the richest biodiversity of its flora in its forest, with numerous tribal inhabitants, is able to contribute a lot from ethnomedicine to the ailing humanity. Cordia macleodii Hook. (Boraginaceae), an ethnomedicinal plant has been highlighted for its wound healing, aphrodisiac and hepatoprotective activities. It is a medium-sized tree, known as Panki/Shikari by the tribals, rarely found in the forests of Orissa, Chhattisgarh and Madhya Pradesh. So far, the plant has been studied neither for its pharmacognostical characters nor for its pharmacological actions except its hepatoprotective activity. Hence, it has been selected for a detailed investigation which includes pharmacognostic study of its leaf to find out the diagnostic characters and preliminary physicochemical analysis. Results of the study will help in identifying the plant pharmacognostically. Presence of alkaloids, glycosides and tannins were found during the study.

Gmelina asiatica Linn (G. parvifolia Roxb.) is a large shrub or a small tree. Roots and aerial parts are used in Ayurvedic medicine and also have ethno-medical uses. Root is reported as adulterant to G. arborea roxb roots. Pharmacognostical characters of root were reported. Owing to the shortage of genuine drug and ever-increasing demands in market, it becomes necessary to search an alternative with equal efficacy without compromising the therapeutic value. Nowadays, it becomes a common practice of using stem. In case of roots phytochemical and pharmacological analysis of stem was reported. However, there is no report on the pharmacognostical characters of stem and to differentiate it from roots. The present report describes the botanical pharmacognostical characters of stem and a note to differentiate it from root. Hollow pith, faint annual rings in cut ends, alternatively arranged macrosclereids and bundle cap fibers, and presence of abundant starch grains and calcium oxalates in pith and in ray cells are the diagnostic microscopic characters of stem. Stem pieces can be differentiated from roots by absence of tylosis.

Ayurveda, the science of life, deals with the drugs of animal, herbal, or mineral origin. Drugs of plant origin occupy more than 90% of the constituents of the Ayurvedic formulations used during treatment. Due to over exploitation and non-availability of medicinal plants, certain classical drugs are being substituted by locally available ethnomedicinal plants that are being claimed to possess similar activity by the tribal and local practitioners. The authentic source of Prishniparni is Uraria picta Desv. (Fabaceae) and is being substituted by Alysicarpus longifolius W. and A. Prodr. (Fabaceae) by some traditional healers of Gujarat (Saurashtra region). Both the plants are locally known by the names Samervo or Pithvan and both have similar characteristics with reference to leaves and flowers (inflorescence type). Pharmacognostical and Phytochemical evaluation of Alysicarpus longifolius W. and A. Prodr has been carried out and results are reported.

According to Thai traditional medicine, Pentace burmanica Kurz. stem bark has been used as crude drug for treating diarrhea. However, the crude drug is also found susceptible to adulteration.
To develop specific standardization parameters of P. burmanica stem bark in Thailand and to determine the (+)-catechin and (-)-epicatechin contents of P. burmanica stem bark by HPLC analysis.
Materials and Methods:
P. burmanica stem barks from various sources throughout Thailand were investigated according to WHO guideline of the pharmacognostic specification. High performance liquid chromatography (HPLC) was performed for (+)-catechin and (-)-epicatechin quantification.
Macroscopic evaluation was demonstrated as whole plant drawing. Microscopic evaluation of stem bark powdered drug showed fragment of fibers, resin masses, tannin masses, starch grain, calcium oxalate, and fragment of parenchyma. Physico-chemical parameters revealed that total ash, acid insoluble ash, loss on drying, and water content should be not more than 3.58, 0.50, 8.40, and 9.70% of dry weight respectively; while ethanol and water soluble extractive values should not be less than 21.90 and 19.06% of dry weight respectively. Both (+)-catechin and (-)-epicatechin were existed in P. burmanica ethanolic extract. Owing to the small amount of (+)-catechin, quantitation of its content was omitted. However, (-)-epicatechin contents was found as 59.74 ± 1.69μg/mg of crude extract.
The pharmacognostic investigations can be used to set the standard parameters of P. burmanica stem bark in Thailand. HPLC method can be applied to determine (+)-catechin and (-)-epicatechin content in plant materials.

Shaliparni is one of the Laghupanchamoola ingredients. Desmodium gangeticum DC. is an accepted source of Shaliparni as per Ayurvedic Pharmacopoea of India (API). Desmodium laxiflorum DC. is the drug commonly used instead of D. gangeticum in the Saurashtra region. The study is an attempt to compare the above said two species on the basis of their pharmacognostical profiles. The macroscopy and microscopy of roots of both plants were studied as per standard procedures. Root powders of both Desmodium species used in the experimental study to ascertain its Rasa by dilution method. Both the species show the same Rasa and Anurasa i.e., Madhura and Kashaya and almost same morphological and microscopical characters like prismatic crystals, starch grains etc. Hence it is concluded that D. laxiflorum may be considered as a substitute for D. gangeticum on the basis of present pharmacognostical study.

People in Indian region often apply Shankhpushpi and other Sanskrit-based common name to Evolvulus alsinoides, Convolvulus pluricaulis, Canscora decussata, and Clitorea ternatea. These are pre-European names that are applied to a medicinal plant. Before the establishment of British rule, like the other books, ayurvedic treatises were also hand written. This might be one of the reasons due to which ayurveda could not stand parallel to the western medicine and an ambiguity is reflected in the interpretation of names and description of drugs found in the books like Charaka Samhita and Sushruta Samhita. The most widespread application of Shankhpushpi is for mental problems, but they have been considered for an array of other human maladies. The present investigation deals with the comparative pharmacognostical evaluation of four ethanobotanicals of Shankhpushpi. A comparative morphoanatomy of the root, stem, and leaves has been studied with the aim to aid pharmacognostic and taxonomic species identification. Various physicochemical, morphological, histological parameters, comparative high-performance thin-layer chromatography (HPTLC), and comparative high-performance liquid chromatography (HPLC), chromatogram of methanolic extract presented in this communication may serve the purpose of standard parameters to establish the authenticity of commercialized varieties and can possibly help to differentiate the drug from the other species. All the parameters were studied according to the WHO and pharmacopoeial guidelines.

Plant species have long been used as principal ingredients of traditional medicine in far-west Nepal. The medicinal plants with ethnomedicinal values are currently being screened for their therapeutic potential but their data and information are inadequately compared and analyzed with the Ayurveda and the phytochemical findings.
The present study evaluated ethnomedicinal plants and their uses following literature review, comparison, field observations, and analysis. Comparison was made against earlier standard literature of medicinal plants and ethnomedicine of the same area, the common uses of the Ayurveda and the latest common phytochemical findings. The field study for primary data collection was carried out from 2006-2008.
The herbal medicine in far-west Nepal is the basis of treatment of most illness through traditional knowledge. The medicine is made available via ancient, natural health care practices such as tribal lore, home herbal remedy, and the Baidhya, Ayurveda and Amchi systems. The traditional herbal medicine has not only survived but also thrived in the trans-cultural environment with its intermixture of ethnic traditions and beliefs. The present assessment showed that traditional herbal medicine has flourished in rural areas where modern medicine is parsimoniously accessed because of the high cost and long travel time to health center. Of the 48 Nepalese medicinal plants assessed in the present communication, about half of the species showed affinity with the common uses of the Ayurveda, earlier studies and the latest phytochemical findings. The folk uses of Acacia catechu for cold and cough, Aconitum spicatum as an analgesic, Aesculus indica for joint pain, Andrographis paniculata for fever, Anisomeles indica for urinary affections, Azadirachta indica for fever, Euphorbia hirta for asthma, Taxus wallichiana for tumor control, and Tinospora sinensis for diabetes are consistent with the latest pharmacological findings, common Ayurvedic and earlier uses.
Although traditional herbal medicine is only a primary means of health care in far-west Nepal, the medicine has been pursued indigenously with complementing pharmacology and the Ayurveda. Therefore, further pharmacological evaluation of traditional herbal medicine deserves more attention.
Ficus microcarpa L. fil. (Syn: Ficus retusa) (Moraceae) is well-known traditional medicinal plant. The bark is used for diverse health ailments in traditional and folklore remedies.
The present study was undertaken to lay down pharmacognostical and phytochemical standards.
Materials and Methods:
Pharmacognostic studies on fresh, dried and powdered bark was carried out to determine it's morphological, anatomical, and phytochemical diagnostic features. Furthermore, major phytoconstituents were identified from the extracts with the help of high performance liquid chromatography (HPLC) study.
The morphology showed to be soft, brittle, rough, shallow vertical, irregularly oriented fissures, curved surface; with splintering, laminated fracture. Microscopically F. microcarpa showed all general characteristics of bark with some distinct differentiation. The phellem is thin and even, phelloderm few cell and rectangular and followed by smaller sclerides, the phloem rays are broad, multi-serrate and showed the scattered bundles of sclerides. The fluorescence and physicochemical standards for bark were established. HPLC analysis showed the predominant presence of therapeutically important phytoconstituents such as oleanolic, betulinic acid, lupeol, β-sitosterol, catechin, and gallic acid.
The bark of F. microcarpa considered equivalent to other Ficus species, such as Ficus virens, Ficus infectoria, Ficus arnottiana, Ficus lacor, and Ficus talboti. However, there is no pharmacognostical and phytochemical reports on F. microcarpa to authenticate and differentiate it from similar species. Present work has described pharmacognostical and phytochemical characteristics of F. microcarpa and diagnostic features to differentiate it.

Plants with high validity for wounds and injuries included Hypericum perforatum, Malva parviflora and Prunella vulgaris. Treatments with high validity against endoparasites included those with Juniperus communis and Pinus ponderosa. Anxiety and pain are well treated with Melissa officinalis and Nepeta caesarea.
Pharmacognostical and preliminary phytochemical studies of Triphala churnam were carried out. The churnam of triphala consists of equal quantities of deseeded fruits of Terminalia chebula, Terminalia bellerica and Emblica officinalis. Triphala is exclusively used in more than 200 drug formulations in Indian system of Medicine. The present study involved the pharmacognostical evaluation of Triphala, in which morphological and powder microscopical characters were established. In addition, physico-chemical parameters such as ash values viz, total ash (10.21± 0.42), acid insoluble ash (2.54 ± 0.06), water-soluble ash (5.46±0.24) and sulphated ash (13.12 ± 0.63), extractive values viz, alcohol soluble extractive (11.20±0.18)) and water-soluble extractive (52.56±2.04), fluorescent analysis and microchmical tests were determined. The preliminary phytochemical study revealed the presence of carbohydrates, reducing sugar and tannins in aqueous extract and carbohydrates, flavonoids and tannins in alcoholic extract. This standardization would be very much helpful for the identification of Triphala churnam to differentiate from other powdered sources.
Cardiospermum halicacabum Linn (Sapindaceae) is an important medicinal plant in the traditional system of medicine, known as karṇasphoṭa. The root of it is officially included in Ayurvedic Pharmacopoeia for its therapeutic uses such as jvara, kuṣṭha, pāṇḍu, kṣaya and sandhivāta etc. As no detailed analysis of macroscopy, microscopy characters of the plant, except root, have been carried out till date, it was thought worth to carry out the detailed macroscopic and microscopic study of leaves and stem, following standard pharmacognostical procedures.
Materials and Methods:
Pharmacognostic studies of C. halicacabum were carried out, and in this, the macroscopic, microscopic, physicochemical, fluorescence and phytochemical analyses were done. Physicochemical parameters such as total ash, moisture content, extractive values were determined by World Health Organization guidelines. The microscopic features of leaf and stem components were observed.
Macroscopically the leaves are bi-ternate, ovate-lanceolate in shape with dentate margin. Microscopically, leaf shows prominent midrib and thin dorsiventral lamina. The midrib shows the presence of epidermal layers, angular collenchyma, palisade cells and vascular strands comprised of thin walled xylem and thick walled phloem elements. The lamina shows prominent, narrow and cylindrical upper epidermis. The upper epidermal cells are large and contain mucilage, whereas lower epidermis possesses thin, small and elliptical epidermal cells. The mesophyll was differentiated into two zones upper and lower. The upper zones show narrow cylindrical palisade cells and lower zone shows 2-3 layers of loosely arranged spongy parenchyma cells. In the Paradermal section of the lamina we observe anomocytic stomata. The transverse section of stem shows a pentagonal appearance with five short blunt ridges and prominent cuticle. Parenchymatous cells, cortical sclerenchyma, lignified xylem fibers, phloem and pit were also found. In the powder microscopy of whole plant, glandular trichomes, non-glandular trichomes, fragments of lamina, xylem elements, parenchyma cells and fibers are observed. Phytochemical screening reveals that the C. halicacabum extract contains glycosides, carbohydrates, flavonoids, phytosterols, phenolic compounds and saponin.
Various pharmacognostic characters observed in this study help in identification, quality, purity and standardization of C. halicacabum.

Ruta graveolens L., is a odoriferous herb belonging to the family Rutaceae. It is the source of Rue or Rue oil, called as Sadab or Satab in Hindi. It is distributed throughout the world and cultivated as a medicinal and ornamental herb. The ancient Greeks and Romans, held the plant in high esteem. It is used in Ayurveda, Homoeopathy and Unani. Phytochemical constituents and pharmacological properties were studied in depth. In 14 species of genus Ruta, R. graveolens and R. chalepensis are available in India and also cultivated in gardens. Taxonomical characters to identify the Indian plants are very clear with fringed and or non-fringed petals. However, references to it are confused in the traditional literature. Due to sharing of regional language name, its identity is confused with Euphorbia dracunculoides. Morphological and anatomical characters were described. Pharmacognostic studies with microscopic characters were also published. Upon reviewing the anatomical characters and pharmacognostic characters one finds that it is highly confused and conflicting. The characters described are opposite of each other and authenticity of the market sample of R. graveolens cannot be guaranteed and able to be differentiated from R. chalepensis. Present work is to describe the pharmacognostic characters of R. graveolens to differentiate it from R. chalepensis. It is concluded that morphologically, R. graveolens can be identified with its non-fringed petals and blunted apices of fruit lobes. Whereas, in R. chalepensis petals are fringed or ciliated and apices of the fruit lobes are sharp and projected. Microscopically, in stem of R. graveolens pericyclic fibers have wide lumen. Whereas, in R. chalepensis, it is narrow. The published pharmacognosy reports do not pertain to authentic plant or some of the characteristic features like glandular trichomes are not observed in our samples.

“Pashanbheda” is a controversial plant. Pharmacopeia considers Bergenia ligulata as official source of Pashanbheda and official substitute is Avera lanta. Review of the literature reveals that 23 different plants are reported in name of “Pashanbheda”. Ammania buccifera is an adulterant, which is used in Kerala under the name of Pashanbheda, found in moist places of India. The present study was undertaken to compare the roots of both the plants and to have a brief view point on similarities and dissimilarities between the plants. The pharmacognostical evaluation reveals that the rosette crystals of B. ligulata are bigger in size compared to that of A. buccifera and cork is present in B. ligulata, whereas it is absent in A. buccifera. HPTLC shows similar Rf values of both the drug, The quantitative estimation showed that total phenol content of both the drug was almost equal.

The beginning of medicinal uses of plants dates back to the scribing period of Vedas in India. In ancient days, such uses came into vogue due to accidental experimentation or observation which subsequently gave rise to practice either by a qualified physician or by an astrologer or by lay men, called nostrum or folk-lore. All these have their own distinct manner of use though they are very often intermingled. Apart from classical uses as mentioned in Ayurvedic, Unani or Sidha therapeutic treatises, material medica, texts on / pharmacy etc.; the new dimension of collecting additional information started in early part of 20th century where on several botanists contributed a lot for exploration of the same.
Since Orissa is a treasure of folk-core claims and besides qualified practitioners, certain lay men especially in rural area and tribal area, saints and priests at different places also possess knowledge on certain typical uses of several plants, there is a larger scope to highlight the same for future study from difference angles. In this paper an attempt has been made to highlight certain newer information's on certain common and uncommon plants like Lygodium flexuosum, Vitex peduncularis, Barleria lupulina, Leptadenia reticulate, Selaginella indica, etc., collected from different parts of Orissa.
The objective of this study is to evaluate the lowering of uric acid using Balanophora laxiflora extracts and derived phytochemicals on potassium-oxonate-(PO-) induced hyperuricemia in mice. The results revealed that ethyl acetate (EtOAc) fraction of B. laxiflora extracts exhibited strong xanthine-oxidase-(XOD-) inhibitory activity. In addition, among the 10 subfractions (EA1–10) derived from EtOAc fraction, subfraction 8 (EA8) exhibited the best XOD-inhibitory activity. Four specific phytochemicals, 1-O-(E)-caffeoyl-β-D-glucopyranose (1), 1-O-(E)-p-coumaroyl-β-D-glucopyranose (2), 1,3-di-O-galloyl-4,6-(S)-hexahydroxydiphenoyl-β-D-glucopyranose (3), and 1-O-(E)-caffeoyl-4,6-(S)-hexahydroxydiphenoyl-β-D-glucopyranose (4), were further isolated and identified from this subfraction. Compounds 3 and 4 exhibited the strongest XOD-inhibitory activity compared with other compounds, and both hydrolyzable tannins were determined to be noncompetitive inhibitors according to the Lineweaver-Burk plot. On the other hand, the in vivo hypouricemic effect in hyperuricemic mice was consistent with XOD-inhibitory activity, indicating that B. laxiflora extracts and derived phytochemicals could be potential candidates as new hypouricemic agents.
Aims of the present study were to investigate effects of Balanophora spicata (BS) on antinociception and anti-inflammation both in vivo and in vitro. Crude extract of BS inhibited vascular permeability induced by histamine, serotonin, bradykinin, and PGE2, but not by PAF. Furthermore, BS crude extract, different layers (n-hexane, ethyl acetate, n-butanol, and water layer), and lupeol acetate had significant antinociceptive and anti-inflammatory effects on acetic acid-induced abdominal writhing response, formalin-induced licking behavior, carrageenan-, and serotonin-induced paw edema. The n-hexane layer had the most effective potency among all layers (IC50: 67.33 mg/kg on writhing response; IC50s: 34.2 mg/kg and 21.29 mg/kg on the early phase and late phase of formalin test, resp.). Additionally, lupeol acetate which was isolated from the n-hexane layer of BS effectively inhibited the acetic acid-induced writhing response (IC50: 28.32 mg/kg), formalin-induced licking behavior (IC50: 20.95 mg/kg), NO production (IC50: 4.102 μM), iNOS expression (IC50: 5.35 μM), and COX2 expression (IC50: 5.13 μM) in LPS-stimulated RAW 264.7 cells. In conclusion, BS has antinociceptive and anti-inflammatory effects which may be partially due to the inhibition of changes in vascular permeability induced by histamine, serotonin, bradykinin, and PGE2 and the attenuation of iNOS and COX-2 expression.
Launaea sarmentosa (Willd) Schultz-Bip.ex Kuntze (Asteraceae), locally known as Kulhafila in the Maldives, is a creeping herb, native to tropical Indian coastlines. According to anecdotal evidence from locals in the Maldives, the roots of this plant are used as an ingredient of a popular medicinal preparation (Hilibeys) taken by mothers after childbirth. It is also used in various other ailments in different parts of the Maldives, as well as in India. So far, there has been no scientific documentation of this plant. The only source of information available is held by natives and traditional medical practitioners. The present study was conducted on the root of L. sarmentosa for its pharmacognostical and phytochemical characteristics as per Ayurvedic Pharmacopoea of India (API) parameters. The microscopic characteristics of the root show prismatic crystals, multiseriate medullary rays, laticiferous cells, and pitted parenchyma. Qualitative analyses, such as loss on drying, ash value, pH, etc., were conducted. Preliminary phytochemical screening shows the presence of alkaloids, tannin, steroids, etc.

Wrightia tinctoria R. Br. belongs to family Apocynaceae commonly called as Sweet Indrajao, Pala Indigo Plant, Dyer's Oleander. “Jaundice curative tree” in south India. Sweet Indrajao is a small, deciduous tree with a light gray, scaly smooth bark. Native to India and Burma, Wrightia is named after a Scottish physician and botanist William Wright (1740-1827). Sweet Indrajao is called dhudi (Hindi) because of its preservative nature. The juice of the tender leaves is used efficaciously in jaundice. Crushed fresh leaves when filled in the cavity of decayed tooth relieve toothache. In Siddha system of medicine, it is used for psoriasis and other skin diseases. Oil 777 prepared out of the fresh leaves of the plant has been assigned to analgesic, anti-inflammatory, and anti-pyretic activities and to be effective in the treatment of psoriasis. The plant is reported to contain presence of flavanoid, glycoflavones-iso-orientin, and phenolic acids. The various chemical constituents isolated from various parts of the plant are reported as 3,4-Seco-lup-20 (29)-en-3-oic acid, lupeol, stigmasterol and campetosterol, Indigotin, indirubin, tryptanthrin, isatin, anthranillate and rutin Triacontanol, Wrightial, cycloartenone, cycloeucalenol, β-amyrin, Alpha-Amyrin, and β-sitosterol, 14α-methylzymosterol. Four uncommon sterols, desmosterol, clerosterol, 24-methylene-25-methylcholesterol, and 24-dehydropollinastanol, were isolated and identified in addition to several more common phytosterols. The Triterpinoids components of the leaves and pods of Wrightia tinctoria also isolated. This article intends to provide an overview of the chemical constituents present in various parts of the plants and their pharmacological actions and pharmacognostical evaluation.

Human influenza is a seasonal disease associated with significant morbidity and mortality. Anti-flu ayurvedic/herbal medicines have played a significant role in fighting the virus pandemic. Plumbagin and allicin are commonly used ingredients in many therapeutic remedies, either alone or in conjunction with other natural substances. Evidence suggests that these extracts are associated with a variety of pharmacological activities.
To evaluate anti-influenza activity from Plumbago indica and Allium sativum extract against Influenza A (H1N1)pdm09.
Materials and Methods:
Different extraction procedures were used to isolate the active ingredient in the solvent system, and quantitative HPLTC confirms the presence of plumbagin and allicin. The cytotoxicity was carried out on Madin-Darby Canine kidney cells, and the 50% cytotoxic concentration (CC50) values were below 20 mg/mL for both plant extracts. To assess the anti-influenza activity, two assays were employed, simultaneous and posttreatment assay.
A. sativum methanolic and ethanolic extracts showed only 14% reduction in hemagglutination in contrast to P. indica which exhibited 100% reduction in both simultaneous and posttreatment assay at concentrations of 10 mg/mL, 5 mg/mL, and 1 mg/mL.
Our results suggest that P. indica extracts are good candidates for anti-influenza therapy and should be used in medical treatment after further research.
The search for natural antiviral compounds from plants is a promising approach in the development of new therapeutic agents. In the past century, several scientific efforts have been directed toward identifying phytochemicals capable of inhibiting virus. Knowledge of ethnopharmacology can lead to new bioactive plant compounds suitable for drug discovery and development. Macromolecular docking studies provides most detailed possible view of drug-receptor interaction where the structure of drug is designed based on its fit to three dimensional structures of receptor site rather than by analogy to other active structures or random leads. Our previous studies indicate that Allicin sand Plumbagin could be used as the potent multi drug targets against the Neuraminidase, Hemagglutinin and M2 protein channel of influenza A (H1N1) pdm09. This in-vittro study has shown that P. indica L. and A. sativum extracts can inhibit influenza A (H1N1)pdm09 virus by inhibiting viral nucleoprotein synthesis and polymerase activity.

Fumaria indica (Hausskn.) Pugsley (Fumariaceae), known as “Fumitory”, is an annual herb found as a common weed all over the plains of India and Pakistan. The whole plant is widely used in traditional and folkloric systems of medicine. In traditional systems of medicine, the plant is reputed for its anthelmintic, diuretic, diaphoretic, laxative, cholagogue, stomachic and sedative activities and is used to purify blood and in liver obstruction in ethnopharmacology. The whole plant is ascribed to possess medicinal virtues in Ayurvedic and Unani systems of medicine and is also used in preparation of important Ayurvedic medicinal preparations and polyherbal liver formulations. The review reveals that phytochemical constituents of wide range have been separated from the plants and it possesses important pharmacological activities like smooth muscle relaxant, spasmogenic and spasmolytic, analgesic, anti-inflammatory, neuropharmacological and antibacterial activities. The separation of hepatoprotective and antifungal constituents from this plant was also reported newly. This review highlights the traditional, ethnobotanical, phytochemical, pharmacological information available on Fumaria indica, which might be helpful for scientists and researchers to find out new chemical entities responsible for its claimed traditional uses.
