摘　　要：对9个广西主产鲜食、野生葡萄品种的葡萄皮多酚类物质含量及其对1,1-二苯基-2-三硝基苯肼(DPPH)自由基和超氧阴离子自由基清除率的影响进行比较研究。结果表明,葡萄皮中多酚类物质含量较高的品种为野生葡萄“野酿2号”毛葡萄和鲜食葡萄“温克”,含量分别为22.63 mg/g和19.77 mg/g。所有品种葡萄皮多酚对DPPH自由基清除率均在85%以上,抗氧化效果显著,但品种间对超氧阴离子自由基清除率差异较大,清除率最高的是“夏黑”(98.3%),其次是“野酿2号”毛葡萄(85.7%),最低的是“甬优一号”(35%)。果皮总酚含量高,同时抗氧化活性优于其他品种的是“野酿2号”毛葡萄、“温克”、“新株系Y137”毛葡萄和“夏黑”4个葡萄品种。The contents of polyphenols substances in peel of 9 table and wild grape varieties which mainly produced in Guangxi province were determined,and their effect on the clearance of 1,1-diphenyl-2-picrylhydrazyl(DPPH)free radical and superoxide anion free radicals were studied.The grape peel with high content of polyphenols were wild grape‘Wild grape No.2’and table grape‘Wenk’,which contained 22.63 mg/g and 19.77 mg/g,respectively.The scavenging rates of DPPH free radicals for all varieties grape peel polyphenols were greater than 85%,and the antioxi⁃dant effect was significant.However,there were great differences in the scavenging rates of superoxide anion free radi⁃cals,the highest scavenging rate was in the‘Summer black’grapes(98.3%),followed by‘Wild grape No.2’grapes(85.7%)and the lowest in the‘Yongyou No.1’grape(35%).The four grape varieties with high content of polyphenols in peel and superior antioxidant activity were‘Wild grape No.2’grape,‘Wenk’grape,‘New strain Y137’grape and‘Summer black’grape.
