The pharmacognostical studies of Oxalis corniculata L. belongs to family Oxalidaceae was done. In macroscopic studies, it is observed that the leaves are green and flowers are yellow color, pseudo umbels, axially, 1-6 flowered bracts two, linear, bracteole, sepals five lanceolate, petals are oblongata in nature apex and emarginated. Leaves are 3-foliate, leaflets obcordate, Chartaceous, pilose base cunate, margin entire. In this plant fruits are capsule in nature, oblong, abrupty tapering above; puberulous seeds are numerous per locule, ovoid transversely. Physicochemical properties are an important parameter in detecting adulteration on improper handling of the drug. In the evaluation of crude drug, ash values, extractive values are important parameters. The estimation of ash value is useful for detecting low- grade products, exhausted drugs and excess of sandy matter. The determination of extractive values with a range of solvents gives information about extractable non-polar and polar as well as total extractable plant constituents. The pharmacognostical studies of the plant were carried out with a focus on bringing out diagnostic characters will be of immense help in the proper identification and standardization of botanical species of the plant drugs. Which play a major role to establish the particular standards and helps to minimize the adulteration of the plant Oxalis corniculata L.
