Phytochemical and antibacterial screening of root extracts of Abroma augusta Linn

Phytochemical studies on the roots of Abroma augusta (A.augusta) revealed the presence of alkaloids, carbohydrates, steroids, tannins and saponins. The petroleum ether, benzene, acetone, chloroform, alcohol and aqueous extracts of roots of A. augusta were screened for antibacterial activity against Escherichia coli (Clinical isolates), Staphylococcus epidermis (MTCC 435), Micrococcus luteus (MTCC 106), Pseudomonas aeruginosa (MTCC 424), B.cereus (MTCC 645), B.pumilus (Clinical isolates), and B.subtilis (MTCC 441). The results of the study showed that petroleum ether extract of roots of A.augusta demonstrated the best antibacterial activity.
