Abstract: Physicochemical proprieties and antioxidant activity of ether extract from Flos chrysanthemi indici were investigated in this study. The yield of dried ether extract from crude materials (dry weight) was 2.15%. The content of carotenoids in dried extract was (165.51 ± 1.42) mg/g. The ether extract was added to four kinds of edible oil including peanut oil, soybean oil, sunflower oil and corn oil to evaluate its antioxidant activity. Our results indicated that the ether extract could effectively inhibit lipid oxidation and displayed a potential antioxidant activity in a dose-dependent manner. Therefore, this ether extract may be considered as a potential antioxidant agent.

Key words: Flos chrysanthemi indici, ether extract, carotenoids, physicochemical proprieties, antioxidant activity
