title: [Studies on chemical constituents of Gaultheria leucocarpa var. Yunnanensis (Franch.) T. Z. Hsu & R. C. Fang].
abstract: OBJECTIVE
  To separate and identify the chemical constituents of the aerial part of Gaultheria leucocarpa var. yunnanensis.
  
  
  METHODS
  The compounds were extracted with solvents, isolated by column chromatography and identified by spectral analysis.
  
  
  RESULTS
  Four compounds were identified as n-dotriacontane and its homologous compound(1), ursolic acid(2), vanillic acid(3), and quercitrin(4).
  
  
  CONCLUSIONS
  The compounds 1, 4 were obtained from the plant for the first time, and 2 and 3 were from above-ground part of the plant for the first time.
