title: [Studies on chemical constituents from stems and leaves of Jasminum lanceolarium].
abstract: OBJECTIVE
  To investigate the chemical constituents in stem and leaves of Jasminum lanceolarium.
  
  
  METHODS
  The constituents of the EtOAc-soluble portion of the 95% ethanol extractive were isolated and purified by means of column chromatographic methods. Compounds were identified by their physical characteristics and spectral features.
  
  
  RESULTS
  Eight compounds were isolated and identified as 5, 7, 3', 5'-tetrahydroxyflavanone (1), (2S)-5, 7, 3', 4'-tetrahydroxyflavan-5-O-beta-D-glucopyranosie (2), mannitol (3), nonacosane (4), trans-p-coumaric acid (5), cis-p-coumaric acid (6), ferulic acid (7) and, trans-cinnamic acid (8).
  
  
  CONCLUSIONS
  Compounds 14 were isolated from this genus for the first time. And compounds 5 and 6 were isolated from this plant for the first time.
