摘要: 用化学发光法研究了葡萄籽和葡萄皮水提物对活性氧超氧阴离子自由基(O2)和羟自由基(·OH)的清除作用,用分光光度法研究了它们对1、1-二苯基-2-苦肼基自由基(DPPH·)的清除作用。实验表明,葡萄籽和葡萄废水提物对以O-2、·OH及DPPH自由基均有较强的清除作用,且呈量效关系,这提示在葡萄籽和葡萄皮中含有抗自由基的活性物质。在三种清除自由基实验中,其抗自由基活性均为鲜葡萄籽>葡萄皮>干葡萄籽

Abstract: he scavenging effects of’ grape seed and .grape peel water extract on active oxygen superoxide radical (d- )and hydroxyl radical (’ OH ) ’were studied by chemiluminescence assay,and their scavenging effect on 1. 1 Diphenyl-1-2-picryl (DPPH ) was studied by spectrophotometry’.The results show’. that scavenging effects of grape seed and grape peel water extracts on O2’ OH and DPPH’ are strong with quantitative relationship.It indecate that there are some anti-free radical substances present in grape seed and grape peel.Their anti-free radical active orders are fresh grape seed;>grape peel>dry grape seed.

Key words: grape seed grape peel scavenging effect radical
