Ten new oleanene-type triterpene oligoglycosides were isolated from Chinese Glycyrrhizae Radix, the dried root of (Glycyrrhiza uralensis)___- (Fischer)___= [Tohoku-Kanzo (in Japanese) from china], and the structures of five oligoglycosides, named licorice-saponins A3 (3__∼), B2 (5__∼), C2 (7__∼), D3 (9__∼), and E2 (<12>__∼), have been determined on the basis of chemical and physicochemical evidence.
从甘草(Glycyrrhiza uralensis)的干燥根茎中分离出十种新的齐墩果烷型三萜寡糖苷,并基于化学和物理化学证据确定了五种寡糖苷的结构,分别命名为甘草皂苷 A3(3__∼)、B2(5__∼)、C2(7__∼)、D3(9__∼)和 E2(<12>__∼)。
