摘要
从云南产德钦红景天Rhodiola atuntsuensis(Praeg.) Fu 的根及根茎中首次分离得到8 个化合物。根据各项光谱数据及化学反应鉴定其中一个新黄酮甙的结构为3 , 5 , 7 , 8 - 四羟基-黄酮4′- 氧- α- L- 鼠李糖吡喃甙, 命名为德钦红景天甙(rhodiolatuntoside, 2) , 另外7 个已知化合物分别是草质素- 8 - 甲醚(herbacetin - 8 - methylether,1) , 槲皮素(quercetin ,3) , 芦丁(rutin,4) , 酪醇(tyrosol,5) , 红景天甙(salidroside,6) , 没食子酸(gallic acid,7) 和β-谷甾醇( - sitosterol,8) 。
One new compound, 3, 5, 7, 8-tetrahydroxyl flavone 4′-O-α-L-rhamnopyranoside named rhodiolatuntoside(2), along with 7 known compounds, herbacetin-8-methyl ether(1), quercetin(3), rutin(4), tyrosol(5), salidroside(6), gallic acid(7)and β-sitosterol(8), which were firstly isolated from Rhodiola atuntsuenseis,was structurally elucidated based on the spectral and chemical data
