Antioxidant Activities of Ethanol Extracts from Ten Kinds of Bee Pollens

Abstract

Abstract: The antioxidatnt activities (Trolox equivalent antioxidant capacity,reducing power,and DPPH· radical scavenging activity) of ethanol extracts from dandelion pollen,wild chrysanthemum pollen,peach pollen,hawthorn pollen,wild ageratum pollen,yellow roses pollen,wild rose pollen,amboyna pollen,mixed pollen and schisandra pollen were studied. The result showed that the ethanol extracts from the ten kinds of bee pollens all exhibit strong Trolox equivalent antioxidant capacities,reducing powers and DPPH· radical scavenging abilities. Therefore,all the ethanol extracts of the ten kinds ot bee pollens are excellent naturala ntioxidants.

Key words: bee pollen, polyphenols, flavonoids, antioxidative activity
