Abstract

Ethanol and Aqueous extracts of ten Indian medicinal plants were tested for their antibacterial properties against Shigella sonei, S. boydi, S. flexeneri, S. dysenteriae and Escherechia coli with disc diffusion, well diffusion, and minimum inhibitory concentration methods. The results showed that the aqueous extract of the bulb of Alium sativum was effective against S. dysenteriae, S. boydi, and E. coli. The Ethanol extract of the rind of Garcinia mangostana showed activity against S. sonei. The results were compared with results obtained using standard antibiotic disc (Chloramphenicol 30 ug/disc and Ciprofloxacin 5 ug/disc). Spectral analysis of the crude aqueous extract of A. sativum and the crude ethanol extract of G. mangostana were carried out.
