摘要

以智利药用植物丹参地上部分中主要的酚类二乙烷类化合物鼠尾草醇1、迷迭香醇2、鼠尾草酸3和20-脱氧鼠尾草醇4为研究材料，通过测定自由基阳离子二苯基-苦酰肼(DPPH)的衰变，测定其抗氧化活性。在相同条件下，所有化合物的抗氧化水平都高于BHT，鼠尾草酸比维生素E更有效。

Antioxidant Capacity of Abietanes from Sphacele Salviae

Carnosol 1 , rosmanol 2 , carnosic acid 3 and 20-deoxocarnosol 4 , the main phenolic abietanes present in aerial parts of the Chilean medicinal plant Sphacele salviae were tested for antioxidant activity of measuring the decay of the radical cation diphenyl-picrylhydrazyl (DPPH). All compounds displayed higher antioxidant levels than BHT under the same conditions and carnosic acid was more efficient than vitamin E.
