Antioxidant substances were extracted from flowers of Aster scaber, Aster maackii, Coreopsis lanceolata and Coreopsis tinctoria using 2 types of extraction methods- ultrasonic wave and reflux, and antioxidant effects were compared. Higher yield of extract was obtained by ultrasonic wave method in all 4 species. Extraction time was different depending on species, but in all 4 species DPPH and ABTS free radical scavenging and ferrous ion chelating activity were higher or similar by ultrasonic wave than reflux method. Content of total polyphenol and flavonoid was mainly higher by ultrasonic wave than reflux method. Longer the treatment, the more the antioxidant activity and bioactive substances. Anti-lipid peroxidation of ultrasonic and reflux extracts obtained from flowers of Aster scaber and Coreopsis lanceolata were compared. Flower extract of Aster scaber obtained by reflux method showed the highest inhibition effect against peroxidation of linoleic acid, but extract of Coreopsis lanceolata obtained by 15-minute ultrasonic extract showed the highest effect. Ultrasonic wave extraction was more economical and efficient method than reflux extraction.
