Abstract

The water-soluble extract of Sanicula graveolens (Apiaceae) and Mutisia friesiana (Asteraceae) showed radical scavenging activity in the DPPH decoloration assay. Bioassay-guided isolation led to caffeic acid derivatives and flavonoids as the main active compounds of both species. After hydrolysis, caffeic acid and quercetin proved to be the bioactive principles of both plants.

摘要

窃衣（伞形科）和弗里西亚鼠尾草（菊科）的水溶性提取物在DPPH脱色试验中表现出自由基清除活性。生物测定导向的分离得到了咖啡酸衍生物和黄酮类化合物作为这两个物种的主要活性化合物。水解后，咖啡酸和槲皮素被证明是这两种植物的生物活性成分。
