杏花花粉中苦杏仁苷的抗氧化性研究

Research on Antioxidative Activities of Amygdlin from Almond Pollen

本实验主要从总抗氧化能力、还原力、清除DPPH自由基、清除羟自由基、抑制卵磷脂氧化等方面,对杏花花粉中的乙醇提取物、苦杏仁苷、苦杏仁苷结晶上清物进行了抗氧化性研究。结果表明:杏花花粉中苦杏仁苷的抗氧化能力,除清除羟自由基以外均低于杏花花粉醇提物和苦杏仁苷结晶上清物。故开发杏花花粉产品只需生产到乙醇提取物就可以达到抗氧化和抗癌的双重功效。

This research mainly studied the antioxidation of amygdlin from almond pollen on general capacity of antioxdation, reducing power, DPPH radical scavenging activity, hydroxyl radical scavenging activity and antioxidative activity in a lecithin liposome system. It was found that the antioxidative and antiradical capacity of the amygdlin from almond pollen were weaker than that of ethanol extracts and supernatant after amygcllin crystallization, except hydroxyl radical scavenging capacity. So the product of ethanol extracts from almond pollen not only possessed the good antioxidative activities but also the antitumor activities.
