title: [Study on Chemical Constituents of Panzeria alaschanica].
abstract: OBJECTIVE
  To study the chemical constituents of the ethyl acetate extract from Panzeria alaschanica.
  
  
  METHODS
  The chemical constituents of ethyl acetate extract from Panzeria alaschanica were isolated and purified by silica gel. Their structures were i- dentified by means of spectra.
  
  
  RESULTS
  Nine compounds were obtained and identified as 7-Methoxy coumarin (1), Isorhamnetin (2), Caf- feic acid (3), 5-Hydroxy-7,3',4'-trimethoxyflavone (4), 5-Hydroxy-7,4'-dimethoxyflavone (5),Kaempferol (6), Isorhamnetin-3-O-β-D- glucoside (7) Kaempferol-3-O-β-D-glucoside (8), and Isorhamnetin-7-O-β-D-glucuronyl-(1-->6)-O-α-L-rhamnoside (9).
  
  
  CONCLUSIONS
  Compounds 1-4,6,7 and 9 are isolated from this plant for the first time.
