采用3种活性氧产生体系诱发膜脂质过氧化为实验模型,观察了黄芪活性提取成分对膜脂质过氧化作用的防护效能。结果表明,黄芪活性提取成分对多种自由基均有良好的清除作用,其中黄芪总黄酮和黄芪总皂甙的作用最佳。
The lipid peroxidation of membrane induced by three kinds of active oxygen production system was used as an experimental model, and the protective effect of active components extracted from Astragalus membranaceus on membrane lipid peroxidation was observed. The results showed that the active components of Radix Astragali had good scavenging effects on various free radicals. Among them, the total flavonoids of Radix Astragali and total saponins of Radix Astragali had the best effect.
