Colorectal cancer is one of the leading causes of cancer death worldwide and is the third most common form of malignancy in both men and women. Several possible colon cancer chemopreventive agents are found in edible plants. Amorphophallus campanulatus (Roxb.) Blume (family: Araceae) is a tuber crop, largely cultivated throughout the plains of India for using its corm as food. This tuber has also been traditionally used for the treatment of abdominal tumors, liver diseases, piles etc. The aim of this study was to evaluate the dose-dependent cytotoxic and apoptosis inducing effects of the sub fractions of A. campanulatus tuber methanolic extract (ACME) viz. petroleum ether fraction (PEF), chloroform fraction (CHF), ethyl acetate fraction (EAF) and methanolic fraction (MEF) on the colon cancer cell line, HCT-15. Antiproliferative effects of the sub fractions of ACME were studied by MTT assay. Apoptotic activity was assessed by DAPI, Annexin V-FITC and JC-1 fluorescent staining. The chemotherapeutic drug, 5-flurouracil (5-FU) was used as positive drug control. The sub fractions of ACME significantly inhibited the proliferation of HCT-15 cells in a dose-dependent manner. In addition, the extracts were found to induce apoptosis and were confirmed by DAPI, Annexin V-FITC and JC-1 fluorescent staining. A pronounced results of cytotoxic and apoptotic activities were observed in the cells treated with 5-FU and CHF, whereas, EAF and MEF treated cells exhibited a moderate result and the least effect was observed in PEF treated cells. Our results suggested that, among the sub fractions of ACME, CHF had potent cytotoxic and apoptotic activity and thus it could be explored as a novel target for anticancer drug development. Furthermore, these findings confirm that the sub fractions of ACME dose-dependently suppress the proliferation of HCT-15 cells by inducing apoptosis.

Amorphophallus is a genus of perennial plants widely distributed in the tropics or subtropics of West Africa and South Asia. Its corms contain a high level of water-soluble glucomannan; therefore, it has long been used as a medicinal herb and food source. Genetic studies of Amorphophallus have been hindered by a lack of genetic markers. A large number of molecular markers are required for genetic diversity study and improving disease resistance in Amorphophallus. Here, we report large scale of transcriptome sequencing of two species: Amorphophallus konjac and Amorphophallus bulbifer using deep sequencing technology, and microsatellite (SSR) markers were identified based on these transcriptome sequences.
cDNAs of A. konjac and A. bulbifer were sequenced using Illumina HiSeq™ 2000 sequencing technology. A total of 135,822 non-redundant unigenes were assembled from about 9.66 gigabases, and 19,596 SSRs were identified in 16,027 non-redundant unigenes. Di-nucleotide SSRs were the most abundant motif (61.6%), followed by tri- (30.3%), tetra- (5.6%), penta- (1.5%), and hexa-nucleotides (1%) repeats. The top di- and tri-nucleotide repeat motifs included AG/CT (45.2%) and AGG/CCT (7.1%), respectively. A total of 10,754 primer pairs were designed for marker development. Of these, 320 primers were synthesized and used for validation of amplification and assessment of polymorphisms in 25 individual plants. The total of 275 primer pairs yielded PCR amplification products, of which 205 were polymorphic. The number of alleles ranged from 2 to 14 and the polymorphism information content valued ranged from 0.10 to 0.90. Genetic diversity analysis was done using 177 highly polymorphic SSR markers. A phenogram based on Jaccard’s similarity coefficients was constructed, which showed a distinct cluster of 25 Amorphophallus individuals.
A total of 10,754 SSR markers have been identified in Amorphophallus using transcriptome sequencing. One hundred and seventy-seven polymorphic markers were successfully validated in 25 individuals. The large number of genetic markers developed in the present study should contribute greatly to research into genetic diversity and germplasm characterization in Amorphophallus.

A Roche 454 cDNA deep sequencing experiment was performed on a developing corm of Amorphophallus konjac—also known as voodoo lily. The dominant storage polymer in the corm of this plant is the polysaccharide glucomannan, a hemicellulose known to exist in the cell walls of higher plants and a major component of plant biomass derived from softwoods. A total of 246 mega base pairs of sequence data was obtained from which 4,513 distinct contigs were assembled. Within this voodoo lily expressed sequence tag collection genes representing the carbohydrate related pathway of glucomannan biosynthesis were identified, including sucrose metabolism, nucleotide sugar conversion pathways for the formation of activated precursors as well as a putative glucomannan synthase. In vivo expression of the putative glucomannan synthase and subsequent in vitro activity assays unambiguously demonstrate that the enzyme has indeed glucomannan mannosyl- and glucosyl transferase activities. Based on the expressed sequence tag analysis hitherto unknown pathways for the synthesis of GDP-glucose, a necessary precursor for glucomannan biosynthesis, could be proposed. Moreover, the results highlight transcriptional bottlenecks for the synthesis of this hemicellulose.

Amorphophallus campanulatus (Roxb.) Blume belonging to the family of Araceae, is a perennial herb commonly known as elephant foot yam. Its tuber has been traditionally used for the treatment of liver diseases, abdominal tumors, piles. The aim of the present study was to evaluate the dose-dependent cytotoxic and apoptosis inducing effects of the sub fractions of Amorphophallus campanulatus tuber methanolic extract (ACME) namely petroleum ether fraction (PEF), chloroform fraction (CHF), ethyl acetate fraction (EAF) and methanolic fraction (MeF) on human liver cancer cell line, PLC/PRF/5. Antiproliferative effects of the sub fractions of ACME were studied by MTT assay. Apoptotic activity was assessed by 4′,6-diamidino-2-phenylindole (DAPI), annexin V- fluorescein isothiocyanate (FITC) and 5,5’,6,6’ tetrachloro-1,1’,3,3’-tetraethylbenzimidazolylcarbocyanine iodide (JC-1) fluorescent staining. The chemotherapeutic drug, 5-flurouracil (5-FU) was used as positive drug control. The sub fractions of ACME were found to produce considerable cytotoxicity in human liver cancer cell line, PLC/PRF/5. In addition, the extracts were found to induce apoptosis and were substantiated by DAPI, annexin V-FITC and JC-1 fluorescent staining. A pronounced results of cytotoxic and apoptotic activities were observed in the cells treated with 5-FU and CHF, whereas, EAF and MeF treated cells exhibited a moderate result and the least effect were observed in PEF treated cells. Furthermore, these findings confirm that the sub fractions of ACME dose-dependently suppress the proliferation of PLC/PRF/5 cells by inducing apoptosis.

• Background and Aims Petioles of huge solitary leaves of mature plants of Amorphophallus resemble tree trunks supporting an umbrella-like crown. Since they may be 4 m tall, adaptations to water transport in the petioles are as important as adaptations to mechanical support of lamina. The petiole is a cylindrical shell composed of compact unlignified tissue with a honeycomb aerenchymatous core. In both parts numerous vascular bundles occur, which are unique because of the scarcity of lignified elements. In the xylemic part of each bundle there is a characteristic canal with unlignified walls. The xylem pecularities are described and interpreted.
• Material Vascular bundles in mature petioles of Amorphophallus titanum and A. gigas plants were studied using light and scanning electron microscopy.
• Key Results The xylemic canal represents a file of huge metaxylem tracheids (diameter 55–200 µm, length >30 mm) with unlignified lateral walls surrounded by turgid parenchyma cells. Only their end walls, orientated steeply, have lignified secondary thickenings. The file is accompanied by a strand of narrow tracheids with lignified bar-type secondary walls, which come into direct contact with the wide tracheid in many places along its length.
• Conclusions The metaxylem tracheids in A. petioles are probably the longest and widest tracheids known. Only their end walls have lignified secondary thickenings. Tracheids are long due to enormous intercalary elongation and wide due to a transverse growth mechanism similar to that underlying formation of aerenchyma cavities. The lack of lignin in lateral walls shifts the function of ‘pipe walls’ to the turgid parenchyma paving the tracheid. The analogy to carinal canals of Equisetum, as well as other protoxylem lacunas is discussed. The stiff partitions between the long and wide tracheids are interpreted as structures similar to the end walls in vessels.

The Titan arum (Araceae) produces the largest bloom of all flowering plants. Its flowering period of two days is divided into a female flowering phase in the first night and a male flowering phase in the second night. Recently, we have documented thermogenesis in the spadix of the Titan arum during the female flowering phase. Here, we document a second thermogenic phase in which the male florets are heated during the male flowering phase. Obviously the two nocturnal thermogenic phases are linked with the two flowering periods. These observations now allow a more detailed understanding of the flowering behavior of the Titan arum.

Background and Aims
Species of Araceae accumulate calcium oxalate in the form of characteristically grooved needle-shaped raphide crystals and multi-crystal druses. This study focuses on the distribution and development of raphides and druses during leaf growth in ten species of Amorphophallus (Araceae) in order to determine the crystal macropatterns and the underlying ultrastructural features associated with formation of the unusual raphide groove.
Transmission electron microscopy (TEM), scanning electron microscopy (SEM) and both bright-field and polarized-light microscopy were used to study a range of developmental stages.
Raphide crystals are initiated very early in plant development. They are consistently present in most species and have a fairly uniform distribution within mature tissues. Individual raphides may be formed by calcium oxalate deposition within individual crystal chambers in the vacuole of an idioblast. Druse crystals form later in the true leaves, and are absent from some species. Distribution of druses within leaves is more variable. Druses initially develop at leaf tips and then increase basipetally as the leaf ages. Druse development may also be initiated in crystal chambers.
The unusual grooved raphides in Amorphophallus species probably result from an unusual crystal chamber morphology. There are multiple systems of transport and biomineralization of calcium into the vacuole of the idioblast. Differences between raphide and druse idioblasts indicate different levels of cellular regulation. The relatively early development of raphides provides a defensive function in soft, growing tissues, and restricts build-up of dangerously high levels of calcium in tissues that lack the ability to adequately regulate calcium. The later development of druses could be primarily for calcium sequestration.

Konjac is one of the most important glucomannan crops worldwide. The breeding and genomic researches are largely limited by the genetic basis of Amorphophallus. In this study, the transcriptomes of A. konjac and A. bulbifer were constructed using a high-throughput Illumina sequencing platform. All 108,651 unigenes with average lengths of 430 nt in A. konjac and 119,678 unigenes with average lengths of 439 nt were generated from 54,986,020 reads and 52,334,098 reads after filtering and assembly, respectively. A total of 54,453 transcripts in A. konjac and 55,525 in A. bulbifier were annotated by comparison with Nr, Swiss-Prot, KEGG, and COG databases after removing exogenous contaminated sequences. A total of 80,332 transcripts differentially expressed between A. konjac and A. bulbifer. The majority of the genes that are associated with konjac glucomannan biosynthetic pathway were identified. Besides, the small RNAs in A. konjac leaves were also obtained by deep sequencing technology. All of 5,499,903 sequences of small RNAs were obtained with the length range between 18 and 30 nt. The potential targets for the miRNAs were also predicted according to the konjac transcripts. Our study provides a systematic overview of the konjac glucomannan biosynthesis genes that are involved in konjac leaves and should facilitate further understanding of the crucial roles of carbohydrate synthesis and other important metabolism pathways in Amorphophallus.
To investigate the phytochemical screening (group determination) and selected pharmacological activities (antioxidant, antimicrobial and analgesic activity) of the plant Sida cordifolia Linn (S. cordifolia).
Eighty percent concentrated ethanol extract of the roots was used. To identify the chemical constituents of plant extract standard procedures were followed. In phytochemical screening the crude extract was tested for the presence of different chemical groups like reducing sugar, tannins, saponins, steroids, flavonoids, gums, alkaloids and glycosides. The antioxidant property of ethanolic extract of S. cordifolia was assessed by DPPH free radical scavenging activity. Analgesic activity of the extract was tested using the model of acetic acid induced writhing in mice. Diclofenac sodium is used as reference standard drug for the analgesic activity test. Antibacterial activity of plant extract was carried out using disc diffusion method with five pathogenic bacteria comparison with kanamycin as a standard.
Phytochemical analysis of the ethanolic extract of the roots of S. cordifolia indicated the presence of reducing sugar, alkaloids, steroids and saponins. In DPPH scavenging assay the IC50 value was found to be 50 µg/mL which was not comparable to the standard ascorbic acid. The crude extract produced 44.30% inhibition of writhing at the dose of 500 mg/kg body weight which is statistically significant (P>0.001). The in vitro antimicrobial activity of the ethanol extract of the roots of S. cordifolia showed no antimicrobial activity against five types of microorganisms. The experiment was conducted only with five species of bacteria as test species, which do not at all indicate the total inactivity against micro-organisms.
The obtained results provide a support for the use of this plant in traditional medicine but further pharmacological studies are required.

In original Ayurvedic classics viz. in Caraka Samhita & Susruta Samhita, thousands of Medicinal plants and their parts are prescribed in various diseases. Medicinal Plants are not available at one place, rather found at different part of our country i.e. Vatsanabha, Jatamansa, Devadaru, in northen India (Himalaya region); Agara, Paga, in Eastern India; Samudraphala, Kupalu, in southern India and Guggalu, Asvagandha, in western India. These are a few examples; many more can be seen in Ayurvedic texts. It is worthy to mention here that seed, root, root bark, stem, stem bark, tuber, rhizome, leaf, flower, exudate, latex, fruit etc. are the various plant parts which are used to prepare medicine in Ayurveda. Further, those parts are not available in one season and also at one Geographical region of our country. To a physician or to a Ayurvedic scholar, it is not possible to see all plants as they are grown in different regions. For proper knowledge they are required to be kept at one place, where one can see and acquire practical knowledge. Thus Museum is the best place to keep them in best condition. Its also essential as per CCIM norms. So all about brief study of dravya guna museums importance, maintenance and related problems & solution is given.

In ethno-medicinal practices, the roots of Cissampelos pareira(Patha) are used in the treatment of various ailments related to urinary problems and skin infections, and in tumorinhibitor activity, antibacterial, antimalarial, diuretic activity,anticonvulsant activity etc., The main problem encountered in standardization of Ayurvedic drugs is proper identification of the source plant.
Materials and Methods:
The macroscopic features of each anatomical component have been observed by a high-resolution camera. The moisture content, total ash, acid-insoluble ash, and water—alcohol and ether extractive values of the powdered sampleswere determined by the method as per WHO guidelines. The phytochemical investigation of the methanolic extract of Cissampelos pareira root was performed by the standard chemical ltests and by TLC on silica gel G using solvent systems proposed by Harborne.
The microscopic characteristics showed the wavy epidermis with unicellular trichomes. Lignified xylem vessels, radial medullary rays, and prismatic calcium oxalate crystals had also been found. Phytochemical screening revealed that the Cissampelos pareira root extract contains terpenoids, alkaloids, tannins, amino acid proteins, and carbohydrates. Alkaloids and essential oil were detected in TLC of the Cissampelos pareira root extract developed using blends of methanol:concentrated ammonia (200:3) and n-butanol:acetone:water (3:1:1) and benzene:ethyl acetate:formic acid(9:7:4) as solvent systems for alkaloid whereas chloroform(100%), benzene (100%), chloroform:benzene(1:1),and ether:benzene(1:1) as solvent systems for essential oil.
These findings will be useful toward establishing pharmacognostic standards on identification, purity,quality, and classification of the plant, which is gaining relevance in plant drug research.

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.

A group of five roots of small plants i.e., Shalaparni, Prshniparni, Brhati, Kantakari and Gokshura or Eranda is known as Laghupanchamula under Mishraka Varga (group of drugs). It is used as such or with Mahat Panchamula i.e., Bilva, Gambhari, Shyonaka, Agnimantha and Patala, constituting Dashamula, a well recognized and popular Ayurvedic preparation or as an ingredient of different dosage forms. Classical texts of Ayurveda differs regarding components of this Mishraka Varga. Four out of five drugs of Laghupanchamula are similar in all the Ayurvedic texts, but either Gokshura or Eranda is considered as the fifth drug. So a comphrenesive review of Veda, Samhita Grantha, Cikitsa Grantha and Nighantus, with regards to synonyms, contents, Guna- Karma, origin of variation in contents and possible thought behind two kinds of Laghupanchamula, to throw light for rational use of either Eranda or Gokshura under Laghupanchamula was conducted. It was observed that both the traditions were in practice however Acharya Kashyapa and Ravigupta were in view of Eranda as a fifth drug of Laghupanchamula where as Acharya Charaka, Sushruta, Vagabhatta, Yogaratnakara and Chakradatta are in favour of Gokshura. Infact, the variation in content depends on the need i.e Dosha, Dushya and Vyadhi.

Not a single drug in Ayurveda has been termed as non-medicinal. This means every Dravya has medicinal value in this world. Jangam dravya is an animal sourced medicine. In samhita Jangam Dravya are described first. So as per Krama Varnan Vichar, Jangam Dravyas are significant in this type. In Ayurvedic literature there is more literature on Audbhid & Parthiva Dravyas. I Total available nighantu: more than 25. Total available Rasa Grantha: about 145. There is no one Grantha on Jangam Dravya which describes their whole information. Jangam Dravyas are described in Ayurvedic literature in different views and in different branches. Gross description is available in Samhitas. But they aren’t in format. They are not compiled according to their Guna Karma, Upayogitwa, Vyadhiharatwa, and Kalpa etc. Their use in Chikitsa is minimal as their ready references are not available, though very much effective. So due to sheer need of compilation of these references this topic was selected for study. The basic need for study of Jangam Dravya is to prepare its whole DATABASE. So through this study Database of Jangam Dravya can be available like Jangam Dravya.
Selection of topic this is a fundamental & literary study, Selection of material, Selection of Database software & font, Collection of data & preparation of Master Chart, Preparation of Database, Interpretation & summarization of data.
So in this paper, we are going to focus on literature availability of jangam dravya with the help of modern technique like Microsoft Excel. And also how we can prepare and use the categorical interpretation of jangam dravya with help of database
Jangam Dravyas are described in Ayurvedic literature in different views and in different branches. Importances of these dravyas are the main key point of this study.
By revealing historical and present plant use, ethnobotany contributes to drug discovery and socioeconomic development. Nepal is a natural storehouse of medicinal plants. Although several ethnobotanical studies were conducted in the country, many areas remain unexplored. Furthermore, few studies have compared indigenous plant use with reported phytochemical and pharmacological properties.
Ethnopharmacological data was collected in the Rasuwa district of Central Nepal by conducting interviews and focus group discussions with local people. The informant consensus factor (FIC) was calculated in order to estimate use variability of medicinal plants. Bio-efficacy was assessed by comparing indigenous plant use with phytochemical and pharmacological properties determined from a review of the available literature. Criteria were used to identify high priority medicinal plant species.
A total of 60 medicinal formulations from 56 plant species were documented. Medicinal plants were used to treat various diseases and disorders, with the highest number of species being used for gastro-intestinal problems, followed by fever and headache. Herbs were the primary source of medicinal plants (57% of the species), followed by trees (23%). The average FIC value for all ailment categories was 0.82, indicating a high level of informant agreement compared to similar studies conducted elsewhere. High FIC values were obtained for ophthalmological problems, tooth ache, kidney problems, and menstrual disorders, indicating that the species traditionally used to treat these ailments are worth searching for bioactive compounds: Astilbe rivularis, Berberis asiatica, Hippophae salicifolia, Juniperus recurva, and Swertia multicaulis. A 90% correspondence was found between local plant use and reported plant chemical composition and pharmacological properties for the 30 species for which information was available. Sixteen medicinal plants were ranked as priority species, 13 of which having also been prioritized in a country-wide governmental classification.
The Tamang people possess rich ethnopharmacological knowledge. This study allowed to identify many high value and high priority medicinal plant species, indicating high potential for economic development through sustainable collection and trade.
