Tephrosia calophylla is an undershrub with tuberous root which belongs to the family Fabaceae. Folklore of southern part of India claims it potentiality in treating various ailments like diabetes, inflammation, ulcers and jaundice. Chemically the plant is found to be a rich source of flavonoids. In the present work a diligent study on the pharmacognostical standardization of the tuberous root is carried out. These evaluation techniques help in ensuring the identity, quality and purity of crude drugs. The detailed anatomical studies revealed the presence of rhytidome, fibres, vessels and parenchymatous cells. The presence of collapsed and non collapsed phloem was found to be tissues of diagnostic importance. The linear measurements performed will assist in distinguishing its varieties. The parameters like proximate and fluorescence analysis were carried out. The constants obtained for these experiments will guide in the identification of the exact species. The qualitative chemical tests showed the presence of different chemical constituents in all the four extracts. This comprehensive pharmacognsotic report will help in the development of a suitable plant profile for Tephrosia calophylla .
