用ＥＳＲ 自旋捕集技术研究了从葡萄籽分离的单体、二聚体和三聚体等多酚类物质对羟基自由基和超氧阴离子的精除作用，并与化学发光法的测定结果进行了比较，得到了较一致的结果，证明葡萄籽中多酚类物质对氧自由基的确有较好的清除作用，这很可能是喝少量葡萄酒有利于身体健康的原因
The ESR spin trapping technique was used to study the effect of polyphenols such as monomers, dimers, and trimers isolated from grape seeds on the removal of hydroxyl radicals and superoxide anions, and the results of chemiluminescence measurement A comparison was made and a more consistent result was obtained, demonstrating that polyphenols in grape seeds do indeed have a good scavenging effect on oxygen free radicals, which is probably the reason that drinking a small amount of wine is beneficial to physical health.
