PHYTOCHEMICAL AND GC-MS STUDIES ONINDIGOFERA LINNAEI LINN.

Indigofera linnaei Linn..is a potential folklore medicinal plant(Fabaceae) used for Aurveda and Siddha systems of medicine. In this study Alkaloids, Carbohydrate Glycoside, Saponin, Flavonoids, tannins and Phytosteroids were identified as the major phytochemical constituents in the methanol,acetone and toluuenefractions of Indigofera linnaei Linn. leaf extract. Their structures were elucidated, on the basis of GC-MS data.2,4,6-Octanerione (9.24%), 4, (methyl cyclopropyl)-1-butene(8.87%), non-ionic acid methyl ester(5.78%), trans-N-methyl-3-oxo-5,6-dimethoxy morphian(9.63%). (IRS, 2SR) 2-Dimethyl (Phenyl) silylpentane-3-ol(7.39%), 2,2-bis (t-phenyl 3,4a€ dimethyl phosphate)(5.84%), 2-cyclopropylenetic acid(6.49%)these different active phytochemicals have been found to possess a wide range of activities. In conclusion Indigofera linnaei Linn. contains biologically active compounds that may serve as candidate for the discovery of new drugs in the treatment of antimicrobial activities.
