title: [Study on quality of flavone in various cultivars of Chrysanthemum morifolium for medicine].
abstract: OBJECTIVE
  To study on dynamic accumulation of various flavone in Chrysanthemum morifolium, in order to appraise the quality of flavone.
  
  
  METHODS
  The extract was hydrolyzed and the flavonoid components were determined by RP-HPLC.
  
  
  CONCLUSIONS
  In the samples from Tongxiang, Tezhongboju showed the highest flavonoids content with the total flavone 9.81%, quercetin 4.17 per thousand and apigenin 17.02 per thousand. In the samples from Sheyang, Hongxinju showed the highest content of luteolin with 6.84 per thousand. In the samples from Jiangning, Tezhongboju showed the highest content of total flavone with 7.59%, Yizhongdabaiju showed the highest content of quercetin with 2.78 per thousand, Sheyangxiaobaiju showed the highest content of luteolin with 4.27 per thousand, Sheyanghongxinju showed the highest content of apigenin with 11.20 per thousand. There were differences in the content of flavonoids among the different cultivars, and the same cultivars showed also different when planted in different areas.
