title: [Chemical Constituents from Semiliquidambar cathayensis Roots].
abstract: OBJECTIVE
  To study the chemical constituents from the roots of Semiliquidambar cathayensis.
  
  
  METHODS
  The roots of Semiliquidambar cathayensis were extracted with 80% ethanol for reflux. Chemical constituents were isolated by silica gel chromatography and Sephadex LH-20 column chromatography from petrol ether part and ethyl acetate part of extracts. Their structures were identified on the basis of physico-chemical characters and spectroscopic analysis.
  
  
  RESULTS
  Eleven compounds were obtained from the roots of Semiliquidambar cathayensis, and identified as 3-acetyl-12-ene-oleanolic acid methyl ester (1), β-sitosterol (2), 3-acetyl-12-ene-oleanol-ic acid (3), 2α,3β-dihydroxy-lup-20(29)-en-28-oic acid (4), (24R)-5α-stignast-3,6-dione (5), betulonic acid (6), stearic acid (7), hexadecanoic acid (8), 3-oxo-olean-12-en-28-oic acid (9), arjunolic acid (10) and daucosterol (11).
  
  
  CONCLUSIONS
  Compounds 1,3 - 6 and 8 are isolated from this genus for the first time.
