Chemical composition and antioxidants of Artemisia herba-alba (Asteraceae)

This study aimed to analysis the composition of Artemisia herba-alba flowers’ essential oils using GC-MS and its antioxidant properties. The inhibitory activity was determined using five different concentrations of essential oil of A. herba-alba flowers extracts. The results showed that the antioxidant activity of total essential oils of A. herba-alba flowers is 97.8% in 20μl/ml, while the lower inhibition was 36.1% in 2μl/ml compared to the standard vitamin E. The lowest inhibitory activity was at a concentration of 2μl/ml if the percentage reached 8.5%. The highest antioxidant activity was recorded at a concentration of 20μl/ml as 93.6%. The inhibition percentage of A. herba-alba found to be 97.8% in 20μg/ml. Total antioxidant capacity of A. herba-alba was y = 4.2592x+15.87, R²=0.912. Artemisia herba-alba had compounds 61 components in its essential oil such as 2-Cyclohexen-1-one, 3-methyl-6-(1-methylethyl) (22.24%), 2-Cyclohexen-1-one, 3-methyl-6-(1-methylethyl) (13.99%), (2S,6R,7S,8E)-(+)-2,7-Epoxy-4,8-megastigmadiene (9.48%), Bicyclo[2.2.1]heptane-2,3-dione, 1,7,7-trimethyl-, (1S) (8.33%), Carbamic acid, monoammonium (8.58%), Isophorone (5.22%) and Camphor (4.66%).
