| 摘 要： | 目的：对丹参水提物的抗氧化活性进行体外研究。方法：分别采用邻苯三酚自氧化法、水杨酸法比色法测定丹参水提物对超氧阴离子、羟基自由基的清除能力，并与阳性对照品VE进行比较。结果：丹参水提物还原能力随浓度增加而增强，对超氧阴离子、羟基自由基均有较强的清除作用，且呈剂量效应关系。结论：丹参水提物有显著的抗氧化活性。

| Abstract: | Objective： To study the antioxidation activity of water-soluble components from Salvia rniltiorrhiza. Method： The scavenging effects on superoxide anion and hydroxyl radical were determined by pyrogallol autoxidation and the salicylic acid colorimetry, respectively. VE was regarded as a positive reference. Results： The reducing power of the extract was enhanced with increasing concentration, and the extract has strong inhibition to superoxide anion and hydroxyl radical. Conclusion： The results reveal that wate-soluble components of Salvia miltiorrhiza have si~aificant antioxidant activity. |
