研究了从山马先蒿中分离的6种苯丙苷，即白藜芦醇苷A和martynoside、毛蕊花苷以及从马先蒿中分离的马先蒿苷A、M和N的清除活性。用自旋俘获法研究了蜘蛛鞘对超氧阴离子和羟基自由基的影响。结果表明，苯丙苷结构中酚羟基的数量与其清除活性有关。含有两个邻二羟基的苯丙苷的清除作用强于含有两个邻羟基甲氧基的化合物。
The scavenging activities of six phenylpropanoid glycosides, i.e. leucosceptoside A and martynoside isolated from Pedicularis aloshanica Maxim, verbascoside, and pediculariosides A, M and N isolated from Pedicularis striata Pall ssp. arachnoidea Franch Tsoong, on Superoxide anion and hydroxyl radicals have been studied by the spin trapping method. The results demonstrated that the number of phenolic hydroxyl groups in the structures of the phenylpropanoid glycosides is related to their scavenging activities. The scavenging effects of the phenylpropanoid glycosides possessing two o-dihydroxyl groups were stronger than the effects of the compounds possessing two o-hydroxy-methoxy groups.
