title: [Study on chemical constituents from Anoectochilus chapaensis].
abstract: OBJECTIVE
  To investigate the chemical constituents from the whole herbs of Anoectochilus chapaensis.
  
  
  METHODS
  The chemical constituents were isolated and purified by repeated column chromatographies with silica gel, Sephadex LH-20 and preparative TLC. Their structures were identified by their physiochemical property and spectral data.
  
  
  RESULTS
  6 compounds were isolated and elucidated as follows: (1) Friedelin, (2) Sorghumol, (3) 5alpha, 8alpha-epidioxyergost-22-en-3beta-ol, (4) Stearic acid, (5) Octadecane and (6) Epifriedelanol.
  
  
  CONCLUSIONS
  Compound (1), (2) and (4) are isolated from this plant for the first time, and compound (3), (5) and (6) are isolated from genera Anoectochilus for the first time.
