Antimicrobial Activity of Compounds from Artemisia campestris.

The antimicrobial activities of several compounds isolated from Artemisia campestris were studied using an agar diffusion technique. At a concentration of 125 µg/ml, six of the extracted compounds inhibited growth of Staphylococcus aureus , three of the compounds inhibited Escherichia coli and two inhibited growth of Proteus vulgaris . Pseudomonas pyocyanea was resistant to all extracted compounds.
