Original Article In vitro Antimicrobial Activity of the Essential Oil of Anaphalis contorta Hook f.

The essential oil was isolated from the aerial parts of Anaphalis contorta Hook. f. (Asteraceae). The antimicrobial activity of the essential oil of A. contorta was screened by using well diffusion method, against human pathogenic bacteria and fungi at different concentrations (0.25 µg/ml, 0.125 µg/ml and 0.062 µg/ml). The oil was found to be active against the microorganism Staphylococcus aureus and Microsporum canis at a concentration of 0.125 µg/ml, while Trichophyton rubrum was more susceptible at 0.062 µg/ml of the essential oil of A. contorta.
