Abstract:

The contents of carotenoids and antioxidant activity of the oils extracted from eight kinds of common bee pollen were determined to analyze the correlation between the two parameters. Results indicated that all the eight bee pollen oils had scavenging effect on DPPH free radicals, but displayed a significant difference (P<0.05) and their IC50 values for scavenging DPPH free radicals ranged from 0.212 to 7.110 mg/mL. Carotenoids was abundantly contained in bee pollen oil and the content of carotenoids was linearly correlated (R2 = 0.8645) with antioxidant activity. These results indicate that carotenoids might be one kind of the predominant antioxidants in bee pollen oil.

Key words: bee pollen, oil, antioxidant activity, carotenoid
