ABSTRACT
The antioxidant potential of methanol extracts and ethyl acetate fractions of 10 Artemisia species was investigated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay. The screening of all extracts showed that the ethyl acetate fractions possessed the highest antioxidant activity. The fractions of A. vulgaris, A. campestris, A. annua, A. alba, A. austriaca were the most active and their scavenging potencies as indicated in IC50 values, being 11.96, 12.50, 15.85, 30.79, 37. 35 μg/ml, respectively. Among the methanol extracts these of A. pontica and A. annua (Bulgarian origin) exhibited the strongest antioxidant capacity—61.27 and 67.45 μg/ml. Five flavonoidglycosides were identified by TLC analysis.
