title: [Studies on chemical constituents of Ervatamia hainanensis].
abstract: OBJECTIVE
  To study the chemical constituents of Ervatamia hainanensis.
  
  
  METHODS
  The compounds were separated and purified by column chromatography with silica gel, and identified by IR, MS, NMR and 2D-NMR.
  
  
  RESULTS
  Five compounds were identified as I (isolariciresinol 9-O-beta-D-glucopyranoside), II (cycloartenol), III (beta-amyrin acetate), IV (beta-sitosterol), V (daucosterol), respectively.
  
  
  CONCLUSIONS
  All the compounds were isolated from this plant for the first time.
