新疆雪莲化学成分研究(Ⅳ)

Studies on the Constituents of Saussurea Involucrata Kar.et Kin(Ⅳ)

前文已报导从新疆雪莲(Saussurea Involucrata Kar.et Kin)中分离出四种黄酮及倍半萜类化合物,本文报导另~倍半萜及黄酮类化合物的分离和鉴定。晶Ⅰ为无色针状结晶,异羟肟酸铁试验显紫红色,红外光谱v_(max)^(KBr)cm^(-1):3440,3390(羟基),1760(γ-内酯),2950(饱和C—H),3050,890(烯烃),1070(醇的C—O).

Two crystals have been obtained from soussitrea involucrata Kar.et Kin.These were identified as 11α,13-dihydrodesacylcynaropicrin and quercetin-3-O-α-L-rhamnoside.
