title: [Study on phenolic constituents of Amomum villosum].
abstract: OBJECTIVE
  To study the chemical constituents of Amomum villosum.
  
  
  METHODS
  Compounds were isolated from the alcoholic extract using polyamide, silica gel, Sephadex LH-20, ODS open column chromatography and other means. Their structures were elucidated according to spectral data and physiochemical properties.
  
  
  RESULTS
  Five compounds were isolated from Amomum villosum. They were identified as: 3-ethoxy-hydroxy benzoic acid (1), vanillic acid-1-beta-D-glucopyranosyl ester (2), isorhamnetin-3-beta-D-glucoside (3), flavanocoumarin (4), isoflavanocoumarin (5).
  
  
  CONCLUSIONS
  Compounds 1-5 are isolated from this plant for the first time.
