title: [Studies on the chemical constituents of MEICHA (II)].
abstract: OBJECTIVE
  To study the chemical constituents of MEICHA.
  
  
  METHODS
  Chromatography and spectroscopic analysis were employed to isolate and elucidate the chemical constituents in the plant.
  
  
  RESULTS
  Seven compounds were obtained and identified as beta3-sitosterol (I), oleanolic acid (II), quercetin (III), Taxifolin (IV), Catechin (V), Querceetin-3-O-alpha-L-rhamnoside (VI) and Gallic acid (VII).
  
  
  CONCLUSIONS
  Seven compounds are isolated from this plant for the first time.
