title: [Chemical constituents from supercritical CO2 extraction of Schisandra chinensis].
abstract: OBJECTIVE
  To study the chemical constituents from the supercritical CO2 extraction of Schisandra chinensis.
  
  
  METHODS
  The compounds were separated and purified by conventional column chromatography and their structures were identified by spectroscopic methods.
  
  
  RESULTS
  Nine compounds were isolated from the supercritical CO2 extraction of Schisandra chinensis, and their structures were identified as chrysophanol(1),schisandrin B(2), β-sitosterol(3), schisandrin C(4),schisandrol A(5), angeloylgomisin H(6), daucosterol(7) 1, 5-dimethyl citrate (8), and shikimic acid (9).
  
  
  CONCLUSIONS
  Compounds 1, 8 and 9 are isolated from Schisandra chinensis for the first time,and compound 1 as an anthraquinone is isolated from this genus for the first time.
