| 摘 要： | 为研究松花粉抗氧化活性,采用HPLC-ECD方法测定了松花粉的水提取物和乙醇(乙醇体积分数为80%)提取物中的酚类化合物的含量。同时评价了其对羟基自由基介导的2-脱氧核糖裂解的保护作用。结果表明:2种提取物中均含有原儿茶酸、咖啡酸、p-香豆酸、阿魏酸和高良姜素,乙醇提取物中含有芦丁、槲皮素和山奈酚。松花粉乙醇提取物中的总酚含量显著高于水提物(P<0.05),但水提取物的还原能力和络合能力显著高于乙醇提取物(P<0.05)。2种提取物对非定位羟基自由基介导的2-脱氧核糖裂解的保护作用均显著高于定位羟基自由基(P<0.05),表明松花粉提取物对羟基自由基介导的2-脱氧核糖裂解的保护作用主要通过清除羟基自由基来实现的,这可能与松花粉提取物中含有大量的酚类化合物有关。

| Abstract: | Antioxidant activities of the pine pollen extracts was studied.Phenolics were extracted from the pine pollen using water and 80% ethanol as solvents.The extracts are analyzed by HPLC-ECD.And the scavenging effects of extracts on hydroxyl radical-mediated 2-deoxyribose degradation were studied.The results revealed that protocatechuic acid,caffeic acid,p-coumaric acid,ferulic acid and galangin could be identified and quantified in both extracts.Rutin,quercetin and kaempferol were identified and quantified in ... |
