Crotalaria longipes Wight & Arn (Family: Fabaceae) is an endemic herb. Crotalaria species have
been reported to contain alkaloids, saponins and flavonoids having antileukemic, antitumour,
antispasmodic, antineoplastic, cardio depressant and hypotensive properties. However, perusal of
literature survey reveals that no published work is available till date on the pharmacognostic
characterization and physico-phytochemical analysis of this conservation concern taxon. Thus the
present study deals in detailed pharmacobotanical, physicochemical, fluorescence analysis and
phytochemical properties of aerial part of Crotalaria longipes. Pharmacobotanical features were
examined by macroscopic and microscopic analysis of fresh leaves and stem. Physicochemical
analysis recorded more acid insoluble ash than water soluble ash. Powdered samples were treated with
different reagents and subjected to fluorescence analysis under ordinary, short and long wavelength
UV light. Phytochemical analysis revealed that the presence of alkaloid, anthraquinone, catachin,
coumarin, flavonoid, phenol, quinone, saponin, steroid, tannin, terpenoid, sugar, glycoside and
xanthoprotein. The above parameters are being accounted for the first time and would present valuable pharmacognostical data of the unexplored endemic species and will also be important
towards establishing right identification and quality standards.
