title: [Study on purification of total peony glycoside with D140 macroporous resin].
abstract: OBJECTIVE
  To study the extraction process of total peony glycoside from Paeonia veitchii Lynvh.
  
  
  METHODS
  The extraction process of total peony glycoside with D140 macroporous resin adsorbent was selected with different condence of ethanol for gradient elution.
  
  
  RESULTS
  The optimum condence was 35% ethanol.
  
  
  CONCLUSIONS
  The extraction ratio of paeoniflorin was >50%, and the extraction process is simple and convenient. The regenaration of resin is easy, this method is advisible.
