Comparative Studies on Antimicrobial Activity of Artemisia Sieversiana Ehrhart. Ex. Willd. and Origanum vulgare L

The present study was carried out to evaluate the antimicrobial potential of Artemisia sieversiana Ehrhart. Ex. Willd. (Asteraceae) and Origanum vulgare L. (Lamiaceae) from their extracts. Solvent ether, petroleum ether, chloroform, acetone, ethanol, benzene and aqueous extracts were tested against the test organisms viz., Bacterial strains (Escherichia coli and Bacillus subtilis) and fungal strains (Mucor hiematis and Aspergillus flavus). Ethanol extract of A. sieversiana had maximum zone of inhibition against E. coli. Whereas, chloroform extract of A. sieversiana showed maximum zone of inhibition against B. subtilis. The ethanol extracts of O. vulgare had maximum inhibition zone against E. coli and B. subtilis. Chloroform extract of A. sieversiana showed highest zone of inhibition against Mucor hiematis The O. vulgare extracts had no much activity against Mucor hiematis and A. flavus. Aqueous extracts of both the plants at different concentration showed no inhibition on the tested organisms due to loss of some active compounds during extraction processes of the sample.
