Two new bidesmoside triterpenoid saponins from the seeds of Momordica charantia L.


ABSTRACT: Two new bidesmoside triterpenoid saponins which were identifed as 28-O-?-D-xylopyranosyl(1?3)-?-D-xylopyranosyl(1?4)-?-L-rhamnopyranosyl(1?2)-[?-L-rhamno-pyranosyl(1?3)]-?-D-fucopyranosyl gypsogenin 3-O-?-D-glucopyranosyl (1?2)-?-D-glucopyranosiduronic acid (C1) and 28-O-?-D-xylopyranosyl(1?4)-?-L-rhamnopyranosyl (1?2)-[?-L-rhamnopyranosyl(1?3)]-?-D-fucopyranosyl gypsogenin 3-O-?-D-gluco-pyranosyl(1?2)-?-D-glucopyranosiduronic acid (C2) were isolated together with two known compounds from the seeds of Momordica charantia L. Their structures were elucidated by the combination of mass spectrometry (MS), one and two-dimensional NMR experiments and chemical reactions.
