title: [Studies on purification process of total flavones from Glechoma longituba with macroporous adsorption resin].
abstract: OBJECTIVE
  To study the purification process of total flavones from Glechoma longituba with macroporous adsorption resin.
  
  
  METHODS
  The eluting power and purified ratio of total flavones were selected as indices, the adsorbility and eluting parameters of the process were studied.
  
  
  RESULTS
  The best result that the purity of total flavones from Glechoma longituba could reach 68. 94% was based on the followings: total flavones content in the liquid-0.383 mg/mL, feeding volume--20 mL, feeding rate--1.0 mL/min, eluting agent-5BV purify water and 10BV 30% ethanol, eluting rate--1.0 mL/min.
  
  
  CONCLUSIONS
  The process is simple and convenient which can be used in the purification of total flavones from Glechoma longituba, it may has a good application foreground.
