Abstract:

The antioxidant activities of ethanol or water extracts from eleven species of natural plants were measured with DPPH (2,2-dipheny1-1-picrylhydrazyl) method, respectively. The results indicated that all of them have antioxidant activities, especially some flavonoids-rich extracts, which show stronger antioxidant activities with dose-effect relationship. Furthermore, the antioxidant activities of bee pollen and propolis extracts are the strongest among all the extract samples.

Key words: bee pollen, propolis, natural plant extract, DPPH, antioxidant activity
