云南山楂果化学成分的研究

THE CHEMICAL CONSTITUENTS OF THE FRUITS OF CRATAEGUS SCABRIFOLIA

从云南山楂的果实中分得10个化物,经光谱分析及化学反应分别鉴定为槲皮素(Ⅰ)、芦丁(Ⅱ)、牡荆素(Ⅲ)、金丝挑甙(Ⅳ)、胡萝卜甙(Ⅴ)、熊果酸(Ⅵ)、氯原酸(Ⅶ)、奎宁酸(Ⅷ)、β-谷甾醇(Ⅺ)及二十九烷醇(Ⅹ)。

Ten compounds were isolated from the fruits of Crataegus scabrifolia.They were identified as quercetin(Ⅰ),rutin(Ⅱ),vitexin(Ⅲ),hyperoside(Ⅳ),daucosterol(Ⅴ),ursolic acid(Ⅵ),chlorogenicacid(Ⅶ),quinic acid(Ⅷ),β-sitosterol(Ⅸ),nonacosanol(X)on the basis of spectral evidence and comparison of authentic samples.
