Two new cucurbitane triterpenes, (23 E )‐7 β ‐methoxycucurbita‐5,23,25‐trien‐3 β ‐ol ( 1 ) and 23,25‐dihydroxy‐5 β ,19‐epoxycucurbit‐6‐ene‐3,24‐dione ( 2 ), and a new D : C ‐friedooleanane triterpene, 3 α ‐[( E )‐feruloyloxy]‐ D : C ‐friedooleana‐7,9(11)‐dien‐29‐oic acid ( 3 ), together with two known D : C ‐friedooleanane triterpenes, 3 β ‐[( 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.
