摘　　要：研究以α-葡萄糖苷酶抑制活性筛选为指导,利用色谱法对藏药薰倒牛降血糖有效部位进行了系统的化学成分分离与结构鉴定,从熏倒牛中分离鉴定了4个单体化合物,分别为:β-谷甾醇(1)、伞形花内酯(2)、槲皮素(3)、5,7,3′-trihydroxy-8,4′,5′-trimethoxyflavone(4)并对分离化合物进行了结构表征及活性研究,为藏药薰倒牛的开发及综合利用提供一定的理论依据。Guided by the screening ofα-glucosidase inhibitory activity,the effective parts of Tibetan medicine Xundiao cattle were systematically separated and identified by chromatography for lowering blood sugar.Four samples were separated and identified from the smoked cattle.The monomer compounds wereβ-sitosterol,umbelliferone,quercetin and 5,7,3′-trihydroxy-8,4′,5′-trimethoxyflavone.The structure characterization and activity study of the isolated compounds provided a certain theoretical basis for the development and comprehensive utilization of Tibetan medicine Xundu Niu.
