The total phenolic content and antioxidant activity of 6 Salvia spp. exudates were measured to find new potential sources of natural antioxidants. Total phenolic content was assessed by a modified Prussian blue method, and the antioxidant activity by two methods: 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging capacity assay and lipoxygenase inhibitory assay. The total phenolic content ranged between 1.3 microg/mg DW (S. fallax) and 74.0 microg/mg DW (S. cacaliaefolia). In the DPPH test, S. cacaliaefolia was more effective than BHT, while in the inhibition of lipid peroxidation all the extracts presented good antioxidant capacity.
对6种鼠尾草属植物渗出物的总酚含量和抗氧化活性进行了测定，以寻找天然抗氧化剂的新潜在来源。采用改良普鲁士蓝法评估总酚含量，通过两种方法评估抗氧化活性：1,1-二苯基-2-苦基肼（DPPH）自由基清除能力测定法和脂氧合酶抑制测定法。总酚含量在1.3微克/毫克干重（法氏鼠尾草）至74.0微克/毫克干重（苣叶鼠尾草）之间。在DPPH试验中，苣叶鼠尾草比丁基羟基甲苯更有效，而在抑制脂质过氧化方面，所有提取物均表现出良好的抗氧化能力。
