Abstract
The present study was undertaken to investigate the antimicrobial activity of some ethnomedicinal plants used by tribes of district Guna, Madhya Pradesh, India. Antimicrobial activity of 04 ethnomedicinal plant extracts were evaluated against three bacterial strains. The collected ethno-medicinal plants were used in folk medicine in the treatment of jaundice, laxatives, ophthalmics, anthelmintics, expectorants, purgative and self-medication. All the tested plants, Acacia arabica, Butea monosperma, Cassia fistula and Cassia tora exhibited antimicrobial activity against one or more of the tested microorganisms, Staphylococcus aureus, Salmonella typhimurium and Streptococcus pyogenes at five different concentrations of 20, 40, 60, 80 and 100 mg / disc. Among the tested plant extracts, ethanolic extracts exhibited a higher degree of antimicrobial activity as compared distilled water extracts. The ethanolic extracts of Acacia arabica and Cassia fistula were most active against Staphylococcus aureus and Salmonella thyphimurium.
