Synergetic antimicrobial potential of ageratum conyzoides and ocimum sanctum essential oil

There is an increasing interest in scientific research and in industry, for medicinal and aromatic plant because of their potential application in medicine and plant disease control measures. In the present study the petroleum, chloroform, and methanol extract of Ageratum conyzoides showed the antimicrobial activity against Bacillus subtilis, Staphylococcus aureus, E. coli and Pseudomonas and extract of Ocimum sanctum also active against the E. coli, S. aureus, B. subtilis and Pseudomonas sp. While the synergetic study showed that the mixture of extract of these two species also has more antimicrobial activity against Pseudomonas aeruginosa and S. aureus. These results suggested the synergetic antimicrobial activity against tested bacterial sp. The present study claimed for further study of these two plants and their synergetic effect to treat various diseases and would be useful against infection resulting from Pseudomonas aeruginosa and S. aureus infection.
