title: [Comparative study on content of chlorogenic acid in Lonicera japonica and L. macranthoides].
abstract: OBJECTIVE
  To exploit and utilize reasonably the abundant natural resources by appraising the medicinal purposes of Lonicera macranthoides Hands-Mazz. through the content of the useful chemical constitutents chlorogenic acid.
  
  
  METHODS
  The content of chlorogenic acid in the flowers of L. macranthoides Hands-Mazz in Human and L. japonica Thunb. in Henan and Shandong was compared by HPLC.
  
  
  RESULTS
  The contents of chlorogenic acid were 4.00% and 4.52% in L. macrathoides from Longhui and Xinning County of Hunan respectively. The contents were 2.20% and 2.46% in L. japonica from Shangdong and Henan respectively.
