The present paper deals with the phytochemical screening of therapeutic importance fromStrychnos potatorumL.f., an important medicinal plant. This study involves the preliminary screening, quantitative determination and the qualitative thin layer chromatographic separation of secondary metabolites from the root, stem bark and seeds (collected and market) ofS.potatorum. Further, HPLC alkaloid profile of the seed has been studied. The generated data has provided the basis for its wide use as the therapeutant both in the traditional and folk medicines.

Abstract:The present paper deals with the phytochemical studies on Bauhinia racemosa Lam., Bauhinia purpurea Linn. and Hardwickia binata Roxb. The phytochemical study of three plants involve preliminary phytochemical studies, physico-chemical studies, quantitative estimation of primary and secondary metabolites, TLC study and HPLC fingerprint study of ethanolic extract of leaves of three plants. In HPLC fingerprint study, the three peaks at a retention time of 15min, 17min and 19min were identical in B. racemosa and B. purpurea which was confirmed by overlaid spectra. The generated data may be useful in suggesting chemotaxonomical interrelation between three plants.
