Phytochemical Screening and Pharmacognostic Properties of Peuraria Phaseoloides Leaves (Roxb) Benth. (Fabaceae) (Published)
Pueraria phaseoloides is an herbaceous twining vine and much branched. It belongs to the family fabaceae. Evaluations of the leaves were carried out to determine the phytochemical, macroscopic, microscopic, chemomicroscopic, and physicochemical analysis using standard methods. The phytochemicals detected in the ethanol leaf extract were alkaloids, saponins, tannins, flavonoids, triterpenoids, cardiac glycoside, carbohydrate and reducing sugar. The macroscopic examination revealed fresh leaves are dark green, glabrous, cuneate, alternate and pubescent. Microscopic examination indicated the presence of calcium oxalate crystals, starch grains, xylem, phloem, trichomes, epidermal cells, collenchyma cells, amphistomatic stomata and reticulate vessels. Chemomicroscopic characters present are starch grains, lignified tissues, calcium oxalate crystals, cystolith, tannin, and cellulose. The physicochemical evaluation indicated 5.8% moisture content, 1.3% total ash value, 0.5% acid insoluble ash value, 1.0% water soluble ash value, 8.0% water soluble extractive value and 6.0% alcohol soluble extractive value. This study is useful in pharmacognostic standardization of this plant.
