| Abstract: | Eight new cucurbitane glycosides, kuguaglycosides A–H ( 1 – 8 , resp.), together with five known analogues, 3β,23‐dihydroxycucurbita‐5,24‐dien‐7β‐yl β‐D ‐glucopyranoside ( 9 ), karaviloside III ( 10 ), karaviloside V ( 11 ), karaviloside XI ( 12 ), and momordicoside K ( 13 ), were isolated from the root of Momordica charantia L. The structures of the new compounds were determined on the basis of spectroscopic and chemical methods. |
