title: [Chemical constituents of unsaponifiable matter from seed oil of Momordica cochinchinensis].
abstract: OBJECTIVE
  To study the chemical constituents of unsaponifiable matter from the seed oil of Momordica cochinchinensis.
  
  
  METHODS
  The fatty oil from the seeds of M. cochinchinensis was extracted with petroleum ether, and the saponification was carried out with potassium hydroxide. The unsaponifiable matter was isolated and purified by silica gel column chromatography, and the structures of their constituents were elucidated by means of IR, MS, 1H-NMR, and authentic chemicals.
  
  
  RESULTS
  Karounidiol (1), isokarounidiol (2), 5-dehydrokarounidiol (3), 7-oxodihydrokarounidiol (4), beta-sitosterol (5), stigmast-7-en-3beta-ol (6), and stigmast-7,22-dien-3beta-ol (7) were elucidated.
  
  
  CONCLUSIONS
  These compounds were found in this plant for the first time.
