Five new compounds have been isolated from the flesh fruits of Momordica charantia and their structures elucidated through spectroscopic studies. These include three pentacyclic triterpenes 13-hydroxy-28-methoxy-urs- 11-en-3-one (momordicin), 13fl,28-epoxy-urs-11-en-3-one (momordicinin), 24-[1'-hydroxy, 1' methyl-2'-pentenyloxyl]-ursan-3-one (momordicilin), a sterol 3fl-hydroxy-stigmasta-5,14-dien-1 &one (momordenol) and a monocyclic alcohol l-hydroxy-l,2-dimethyl-2-[8",lO'-dihydroxy-4',7'-dimethyl-ll'-hydroxy methyl-trideca]-3-ethyl-cyclohex-5-en-4-one (momordol).
