Article abstract of DOI:10.1248/cpb.44.1680

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 physicochemical evidence, including syntheses of (11S)-(+)- and (11R)-(-)- jalapinolic acid (16b and 18b) and the glycosidic acid designated as merremoside i (6).
