Prelimnary phytochemical studies in the leaf, stem and root extracts of the traditional medicinal plant species, Thalictrum Javanicum Blume
The leaf, stem and root parts of the traditional medicinal plant species, Thalictrum javanicum are effectively used against the disorder, haematuria and the roots are prescribed as diuretic, purgative and tonic by the local healers of high hills of Nilgiris, the Western Ghats, India. As there is no work in phytochemical constituents, the present study was aimed at to know the available major secondary metabolites in the study species, T. javanicum by preliminary analysis including TLC. The results of the study report the presence of the many major secondary metabolites viz., tannins, saponins, resins, flavonoids, alkaloids, glycosides, terpenoids, cardiac glycosides and triterpenoids in the three parts studied altogether. Among the alcoholic solvents attempted, the methanol extract contained rich number of secondary metabolites than the other solvents used. The mobile phases for the separation of various secondary metabolites were also standardized. The presence of different varieties of secondary metabolites of medicinal importance confirmed the traditional knowledge of local healers of high hills of Nilgiris on medicinal uses of this species.
Key words: Thalictrum javanicum, secondary metabolites, TLC.
