Three Salvia species have been studied for antioxidant activity in methanol extracts from roots and leaves. The presence of the polyphenols and tanshinones was screened by HPLC and spectrophotometric assays and related to the antioxidant potential. The antioxidant capacity of the studied species is high, but differences between species and organs have been also revealed. Salvia przewalskii leaf extract was the strongest one in all tests, followed by Salvia miltiorrhiza root and Salvia verticillata leaf. Among the roots, the most active was S. miltiorrhiza extract, followed by S. verticillata. The antioxidant activity correlates to the total polyphenol and, depending on the assay, to the hydroxycinnamic acids content. The high content of tanshinones in both S. miltiorrhiza and S. przewalskii roots is unlikely to contribute to the antioxidant activity.
对三种鼠尾草属植物的根和叶的甲醇提取物的抗氧化活性进行了研究。通过高效液相色谱法（HPLC）和分光光度法测定筛选了多酚和丹参酮的存在情况，并将其与抗氧化潜力相关联。所研究物种的抗氧化能力较高，但也揭示了物种和器官之间的差异。在所有测试中， przewalskii鼠尾草叶提取物的抗氧化能力最强，其次是丹参根和轮叶鼠尾草叶。在根中，最具活性的是丹参提取物，其次是轮叶鼠尾草。抗氧化活性与总多酚相关，并且根据测定方法的不同，还与羟基肉桂酸含量相关。丹参和przewalskii鼠尾草根中丹参酮的高含量不太可能对抗氧化活性有贡献。
