Screening of chemical composition, antimicrobial and antioxidant activities of Artemisia essential oils

The chemical composition of essential oils isolated from aerial parts of seven wild sages (Artemisia sp.) grown in Western Canada was investigated by GC-MS. The oils had inhibitory effects on the growth of bacteria, yeast, dermatophytes, Fonsecaea pedrosoi and Aspergillus niger. In addition, antioxidant and radical scavenging activities were determined.
