Abstract

Five new resin-glycosides, named merremosides a (1), b (2), c (3), d (4), and e (5), were isolated from the tuber of Merremia mammosa (LOUR.) HALLIER f. (Convolvulaceae), an Indonesian medicinal plant. The structures of 1, 2, 3, 4, and 5 have been elucidated on the basis of chemical and physiochemical evidence, including syntheses of (11S)-(+)- and (11R)-(--)-jalapinolic acid (16b and 18b) and the glycosidic acid designated as merremoside i (6).

摘要

从印度尼西亚药用植物旋花科植物圆锥飞蛾藤（Merremia mammosa (LOUR.) HALLIER f.）的块茎中分离出了五种新的树脂糖苷，分别命名为美雷莫苷a（1）、b（2）、c（3）、d（4）和e（5）。根据化学和物理化学证据阐明了1、2、3、4和5的结构，包括(11S)-(+)-和(11R)-(-)-加拉平醇酸（16b和18b）以及命名为美雷莫苷i（6）的糖苷酸的合成。
