Pharmacognostical and phytochemical standardization of seeds of Strychnos potatorum Linn. (Loganiaceae)

Abstract

In traditional system of medicine, plants with medicinal activity play a major role in curing diseases. Now-a-days, usage of herbal medicines is increasing globally for the treatment of diseases. Plants have been evaluated for their potential benefits. In the present study, pharmacognostical and phytochemical standardization of seeds of Strychnos potatorum Linn. (Loganiaceae) was carried out. The pharmacognostical evaluation was performed for proper identification and to detect the adulterants. Physicochemical analysis like ash value (Total ash – 1.98% w/w, acid-insoluble ash – 0.5% w/w, water soluble ash – 0.99% w/w, sulphated ash – 1.02% w/w), extractive value (water soluble - 9.26% w/w, alcohol soluble - 6% w/w), loss on drying (7.11% w/w) and iron content (1.85% w/w) was estimated. Phytochemical study characterizes the phytoconstituents present in this plant. Evaluation of the seed of Strychnos potatorum ensures identity and ascertains quality and purity of this drug.
