| Abstract: | Two new cucurbitane triterpenes, (23E)‐7β‐methoxycucurbita‐5,23,25‐trien‐3β‐ol ( 1 ) and 23,25‐dihydroxy‐5β,19‐epoxycucurbit‐6‐ene‐3,24‐dione ( 2 ), and a new D : C‐friedooleanane triterpene, 3α‐(E)‐feruloyloxy]‐D : C‐friedooleana‐7,9(11)‐dien‐29‐oic acid ( 3 ), together with two known D : C‐friedooleanane triterpenes, 3β‐(E)‐feruloyloxy]‐D : C‐friedooleana‐7,9(11)‐dien‐29‐oic acid ( 4 ) and 3‐oxo‐D : C‐friedooleana‐7,9(11)‐dien‐29‐oic acid ( 5 ), were isolated from the stems of Momordica charantia. The structures of the new compounds 1 – 3 were determined by spectroscopic methods. |
