Four new triterpene-glycosides, named gongganosides D (4), E (5), F (6), and G (7), and two new secoiridoid-glucosides, (7R)-7-caffeoyloxysweroside (8) and (7S)-7-caffeoyloxysweroside (9), were isolated from the bark of the Indonesian medicinal plant Bhesa paniculata (Celastraceae). The chemical structures have been elucidated on the bases of their chemical and physiocochemical properties.
四个新的三萜糖苷,分别称为gongganosides D(4),E(5),F(6)和G(7),以及两个新的secrididoid-glucosides(7R)-7-caffeoyloxysweroside(8)和(7S)从印度尼西亚药用植物Bhesa paniculata(Celastraceae)的树皮中分离出-7-咖啡酰酰氧基苦味甙(9)。已根据其化学和物理化学特性阐明了化学结构。
