Traditionally used by the tribal of Rajasthan to prevent conception. Roots are used as appetizer, aphrodisiac, brain tonic, cardiotonic and to treat insanity and synovitis. Leaves, seeds preparations are used to treat epilepsy, diarrhea and nootropic. Leaf materials were collected, dried and coarsely powdered and were subjected to physiochemical constants, behavioral characters of the leaf powder with chemical reagents. Pharmacognostical studies include macroscopical, microscopical observations. Physical chemical constants such as ash values, extractive values, loss on drying, foreign organic matter were determined. Ash values include total ash; acid insoluble and water soluble ash were observed. Extractive values of powder with solvents such as petroleum ether, chloroform, ethyl actetae, ethanol and water were determined. Macroscopical characters help in identifying the leaf. Anatomical observations showed the presence of trichomes, upper and lower epidermal cells with rubiaceous stomata. Sclerenchyma fibers and acicular crystal were observed. The percentage of total ash values (4.3, 1.6 and3.94 %) yield of petroleum ether, ethyl acetate, chloroform, ethanol and water showed 3.16,6.4,5.8,10.2 and 7.6% respectively. Preliminary phytochemical screening reported the presence of alkaloids, tannins, phenolic compounds, glycosides and flavanoids.The reported phytoconstitutents of the plant Argyreia nervosa may be responsible for the pharmacological activities. The results obtained add credit to the existing traditional information which will further increase the usage of this plant and provokes towards the investigation of the plant.
