Abstract: The aim of this study was to investigate the distribution of phenolic compounds in bee pollen and their antioxidant activity. Total phenolic content,total flavonoid content,reducing power and DPPH free radical scavenging activity of four states of the extracts( free,esterified,glycosided,and insoluble) of Aceraceae,Taeaxacum and Crataegus pinnatifida bee pollen were determined. The results showed that distribution of phenolic compounds in three kinds of bee pollen was different. Phenolic compounds free state and esterified sate were higher than in glycosided and insoluble state. Therefore,the antioxidant activity of the former was greater than the latter. In addition,the content of phenolic compounds in different bee pollen was different. Phenolic compounds in bee pollen of Aceraceae were higher than others. The order of antioxidant activities of three kinds of bee pollen was Aceraceae > Crataegus pinnatifida >Taeaxacum.
