title: [Studies on constituents in Uncaria macrophylla Wall].
abstract: OBJECTIVE
  To study the chemical constituents of Uncaria macrophylla.
  
  
  METHODS
  Compounds were isolated by Columu Chromatography, and the structures were identified by NMR spectral data and other methods.
  
  
  CONCLUSIONS
  Six compounds were isolated and identified as ursolic acid, 3 beta-6 beta-23-trihydroxyurs-12-en-28-oic acid, 3 beta, 6 beta, 19 alpha-trihydroxyurs-12-en-28-oic acid, epicatechin, beta-sitosterol and daucosterin. All the compounds were isolated for the first time from the plant.
