Abstract

Abstract: The total flavonoids and total phenolic acids were extracted by ultrasonic-assisted extraction. The ABTS⁺ free radical and DPPH free radical scavenging experiments were used to study the antioxidant capacity of extracts from Artemisia argyi in different years. The results showed that the contents of total flavonoids and total phenolic acids in fresh Artemisia argyi, Artemisia argyi stored for one year, Artemisia argyi stored for three years and residue of Artemisia argyi stored for three years were significantly different. Among them, the contents of total flavonoids and total phenolic acids were highest in Artemisia argyi stored for three years, and it had a strong antioxidant activity. Next was Artemisia argyi storage for one year. The content of total flavonoids and total phenolic acids in fresh Artemisia argyi was the lowest and the scavenging effect on free radicals was relatively low. The correlation study showed that there was no significant correlation between total flavonoids and total phenolic acids content and antioxidant activity evaluated by DPPH and ABTS⁺.

Key words: Artemisia argyi, total flavonoids, total phenolic acids, antioxidant activity, correlation
