“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.

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.

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.

Brahmi is a well-known herbal drug having an effect on brain as a memory enhancer. Bacopa monnieri (L.) Pennel and Bacopa floribunda (R.Br.) Wettst are both marketed in the name of Brahmi. The present study differentiates Bacopa monnieri and Bacopa floribunda in morphology, transverse section (T.S.) of root and leaf, powder microscopy, and chemical constituents. Morphological characters show color difference in flower, stem and leaf and differences in microscopic study, organoleptic study, and powder characteristics. Morphologically, Bacopa monnieri leaf is fleshy and more succulent than Bacopa floribunda leaf. There is also a difference in the interval of the stem internodes of the two. Physico-chemical analysis revealed presence of 26% bacoside A in Bacopa floribunda leaf and 27% in Bacopa floribunda stem, which is higher than the bacoside A content in leaf (22%) and stem (18%) of Bacopa monnieri. However due to the hemolytic action of bacoside A, which is the toxic effect of the chemical constituent, it seems likely that Bacopa monnieri is more popular in regular use than Bacopa floribunda.

Cissus repanda Vahl. belongs to the family Vitaceae, commonly known in Hindi as “Panivel,” is a large climber distributed all over India. The crushed or powder of root is prescribed by tribal people and traditional medical practitioners of Orissa for its healing properties in cases of bone fracture, cuts and wounds, swellings, and so on. In spite of its reputation, its leaves have not been investigated scientifically. The present study deals with pharmacognostical and molecular characterization by Random Amplified Polymorphic DNA (RAPD) markers and their role in laying down standardization and pharmacopoeial parameters. Genomic isolation of DNA from fresh leaves was amplified by RAPD markers. The diagnostic characters are mucilage, calcium oxalate rosette crystals, spiral vessels, and fibers. The unique bands obtained in Polymerase Chain Reaction (PCR) amplification clearly discriminated having, many bright and light bands indicating the genuinity of the plant. RAPD may serve as a complementary tool in quality control of many herbal sources.
