摘要:

利用分光光度法对5 种不同品牌的市售葡萄酒的还原性、清除羟自由基、过氧化氢、亚硝酸根离子、超氧阴离子自由基的活性进行了测定。结果表明:我国目前市售的国产葡萄酒具有不同程度的还原性以及清除羟自由基、过氧化氢、亚硝酸根离子、超氧阴离子自由基的活性。葡萄酒中原花青素含量对葡萄糖酒的还原性、清除羟自由基、过氧化氢的能力呈现极显著的正相关性。但是葡萄酒清除亚硝酸根离子、超氧阴离子自由基的活性与葡萄酒中原花青素含量的相关性不显著。

关键词: 葡萄酒, 原花青素, 多酚类, 自由基, 分光光度法

Abstract:

This study investigated the radical scavenging activity including·OH, H2O2, NO2, and O2· and reducing power of five brands of commercial grape wines made in China by spectrophotometry. All the brands of grape wines had varying radical scavenging activities and reducing powers. The activities of scavenging ·OH and O2· radicals and the reducing power were significantly positively correlated to the procyanidin content, respectively while no significant correlation of the procyanidin content was found to the scavenging activities to NO2 and O2· radicals. This might be due to the synergetic effect of procyanidins and other phytochemicals contained in grape wines and further studies need to be done to make clear the mechanisms of radical scavenging activity of grape wines.

Key words: grape wine, procyanidins, polyphenolic phytochemicals, radicals, spectrophotometry
