虎杖为蓼科植物(Polygonumcuspidatum Sieb.et.Zucc.)的干燥根茎。其所含二苯乙烯类化合物白黎芦醇甙具有降血脂、抑制肝损害的作用。本文以卵磷脂脂质体为人工细胞模型,Fe~(2+)和抗坏血酸为自由基发生系统,硫代巴比妥酸显色,采用丙二醛(MDA)法测定白黎芦醇甙对自由基发生系统引起的脂质过氧化的抑制作用。我们经水提醇沉、乙酸乙酯萃取等一系列
Polygonum cuspidatum is a dry rhizome of Polygonumcuspidatum Sieb.et. Zucc. Its stilbene compound, resveratrol, has the effect of reducing blood fat and inhibiting liver damage. In this paper, the lecithin liposome is used as an artificial cell model, Fe~(2+) and ascorbic acid are the free radical generating systems, thiobarbituric acid is developed, and the malondialdehyde (MDA) method is used to determine the resveratrol glycosides. Inhibition of lipid peroxidation by free radical generating systems. We have a series of water extraction, alcohol precipitation and ethyl acetate extraction.
