摘　　要：对油菜蜂花粉酶解物和水提物进行了体外抗氧化实验。结果表明,花粉酶解物具有良好的抗氧化功能,在50mg/ml浓度下对超氧阴离子自由基、羟自由基和脂质过氧化的抑制率分别达到87．4%、61．2%和95．9%。比较酶解物和水提物抗氧化性能可知,酶解物清除羟自由基和超氧阴离子自由基的能力明显高于水提物,在50mg／ml时,对羟自由基的抑制率比水提物高约30%,清除超氧阴离子自由基的能力高约20%,而抑制脂质过氧化的能力与水提物之间无明显差异。Abstract： Antioxidant activity of enzymatic hydrolysates of bee collected rape pollen （BCRP） was studied in vitro. Superoxide anion radical, hydroxyl radical and lipid peroxidation are found to be inhibited by 87.4%, 61.2% and 95.9% respectively with the concentration of enzymatic hydrolysates of BCRP at 50 mg/ml. Compared with the water extract of BCRP, the enzymatic hydrolysates of BCRP demonstrate higher capabilities in scavenging superoxide anion radicals and hydroxyl radicals and similar effects in the inhibition of lipid peroxidation.
