title: [Study on dynamic accumulation of flavone in various Chrysanthemum morifolium for medicine].
abstract: OBJECTIVE
  To study the dynamic accumulation of flavonoids in Chrysanthemum morifolium in order to chose the optimal harvest time.
  
  
  METHODS
  The flavonoid content was determined in various C. morifolium and in different periods.
  
  
  CONCLUSIONS
  The accumulation of flavonoid in various Chrysanthemum reached a high level when lingulate flowers were in 50% blossom and tube ones in 30% or lingulate flowers were in 70% blossom and tube ones in 50%. Only few of C. morifolium reached a high level of flavonoid, when 1 both ingulate and tube flowers blossomed fully.
