摘要: Abstract Five new compounds have been isolated from the fresh 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), 13β,28-epoxy-urs-11-en-3-one (momordicinin), 24-[1′-hydroxy,1′-methyl-2′-pentenyloxyl]-ursan-3-one (momordicilin), a sterol 3β-hydroxy-stigmasta-5,14-dien-16-one (momordenol) monocyclic alcohol 1-hydroxy-1,2-dimethyl-2-[8′,10′-dihydroxy-4′,7′-dimethyl-11′-hydroxy methyl-trideca]-3-ethyl-cyclohex-5-en-4-one (momordol).
