Abstract Three new flavonol glycosides, isorhamnetin 3-(2t´-acetyl) glucoside, limocitrin 7-glucoside, and limocitrin 3,7-diglucoside, were isolated from the aerial parts of Sedum acre. The known compounds quercetin, isorhamnetin and their 3- and 3,7-di-glucosides, isorhamnetin7-glucoside and limocitrin and its 3-glucoside were also identified. The structure of the compounds was determined by means
摘要 从景天的地上部分分离到了三种新的黄酮醇苷,即异鼠李素3-(2t´-乙酰)葡萄糖苷、limocitrin 7-glucoside 和limocitrin 3,7-diglucoside。已知化合物槲皮素、异鼠李素及其 3- 和 3,7- 二糖苷、异鼠李素 7-葡萄糖苷和利莫替林及其 3-葡萄糖苷也被鉴定出来。化合物的结构是通过光谱和化学方法确定的。
