ABSTRACT: The antimicrobial properties of Indian antidiabetic plant extracts of Syzygium cumini, Azadirachta indica and Bougainvillea spectabilis, against six bacterial strains (Escherichia coli, Bacillus subtilis, Staphylococcus aureus, Klebsiella pneumonia, Pseudomonas aeruginosa and Proteus vulgaris). The collected antidiabetic plants Syzygium cumini, Azadirachta indica, and Bougainvillea spectabilis were used as hypoglycemic plants in West Indies and some parts of Asia. Chloroform, ethanol and aqueous extracts were prepared sequentially from leaves of these plants. It was observed that methanol and ethanolic extracts of Syzygium cumini have significant activity against gram positive bacteria. Klebsiella pneumonia and Proteus vulgaris were more sensitive to the extracts of Azadirachta indica and Bougainvillea spectabilis respectively.

KEYWORDS: Syzygium cumini; Azadirachta indica; Bougainvillea spectabilis; ethanol Gram positive
