title: [Chemical Constituents in Petroleum Ether Extract of Mongolian Medicine Halenia corniculata].
abstract: OBJECTIVE
  To study the chemical constituents of Mongolian medicine Halenia corniculata.
  
  
  METHODS
  Positive phase and reversed phase silica gel, as well as Sephadex LH-20 methods were used to separate and purify. The structure of the isolated constituents was identified according to the NMR spectroscopy data and the literature data.
  
  
  RESULTS
  Nine compounds were isolated from 95% ethanol extracts of petroleum ether part of Halenia corniculata and identified as: 1-hydroxy-2,3,4,6-tetramethoxyxanthone (1), 1-hydroxy-2,3, 5-trimethoxyxanthone (2) 1-hydroxy-3,7-dimethoxyxanthone (3), 1-hydroxy-3,5,6,7,8-pentamethoxyxanthone (4), 1-hydroxy-2,3,4, 7-tetramethoxyxanthone (5), 1-hydroxy-3,5-dimethoxyxanthone (6),1-hydroxy-2,3,4,5,7-pentamethoxyxanthone (7), palmitic acid (8) and β-sitosterol (9).
  
  
  CONCLUSIONS
  Compounds 3, 4 and 8 are isolated from this genus for the first time, Compound 1 is isolated from this plant for the first time.
