title: [Studies on involatile constituents of Mentha haplocalyx].
abstract: OBJECTIVE
  To promote its comprehensive utilization, the involatile constituents of Mentha haplocalyx were studied systematically.
  
  
  METHODS
  The chemical components were isolated and purified by silca gel column chromatography and recrystallization. The chemical structures were elucidated on the basis of physico-chemical properties and spectral data.
  
  
  RESULTS
  Eight compounds were isolated and identified as: acacetin (I), tilianine (II), linarin (III), n-butyl-beta-D-fructopyranoside (IV), ursolic acid (V), oleanolic acid (VI), beta-sitosterol (VII), daucosterol (VIII).
  
  
  CONCLUSIONS
  Compounds I approximately V were obtained from this plant for the first time.
