title: [Comparative study on internal quality of four cultivars of Chrysanthemum morifolium].
abstract: OBJECTIVE
  To study the genetic diversity of C. morifolium on the chemical constituents.
  
  
  METHODS
  Chemical constituents of four cultivars cultivated with the same conditions were compared in three types of index: chlorogenic acid, flavonoid and volatile oil.
  
  
  CONCLUSIONS
  With different cultivars and processing methods, the contents of chlorogenic acid, flavonoid and volatile oil extracted from C. morifolium vary great extent.
