自乌拉尔甘草(Glycyrrhiza uralensis Fisch.)根茎中提取皂甙。经盐酸甲醇水解,柱层分离,得到七个皂甙元。本文报道新三萜皂甙元乌拉内酯(uralenolide)及18α-羟基甘草次酸甲酯的结构鉴定。后者为首次得自乌拉尔甘草。
Saponins were extracted from the roots of Glycyrrhiza uralensis Fisch. The methanol was hydrolyzed with methanol and the column was separated to obtain seven saponins. This paper reports the structure identification of uralenolide and 18α-hydroxyglycyrrhetinic acid methyl ester. The latter was obtained for the first time from Ural licorice.
