摘要
利用化学发光及分光光度法研究了刺梨黄酮对活性氧自由基O2-.,H2O2,DPPH·的清除作用,以及对H2O2诱导的红细胞氧化溶血和肝组织脂质过氧化产物(MDA)形成的抑制作用。结果表明,刺梨黄酮能很好地清除各种活性氧,并能显著抑制红细胞氧化溶血以及肝组织MDA的产生。提示其是一种很好的抗氧化剂。
The chemical light assay and the eolorimetric assay were used to detect the oxygen radicals scavenging eapaeity of flavonoids from Rosa roxburghii Tratt. The effect of flavonoids from Rosa roxburghii Tratt. on oxidative erythroeyte and malondialdehyde（MDA）in rat hepatoeyte were investigated. The result showed that flavonoids of Rosa roxburghii Tratt. eould strongly scavenge the oxygen radicals, inhibit the erythrocyte oxidative damage, and deerease the eontent of MDA in rat hepatoeyte remarkably. Fiavonoids of Rosa roxburghii Tratt. is a potential antioxidant.
