title: [Study on Commercial Specification of Lonicerae Japonicae Flos].
abstract: OBJECTIVE
  To provide the basis data for the institute of commercial specification standard of Lonicerae Japonicae Flos.
  
  
  METHODS
  39 samples of Lonicerae Japonicae Flos commercial of different grades in market were collected, and vernier caliper and electronic balance were used to measure the numbers of flower bud and blooming rate per 0. 5 g, contamination content, browning degree, milden and rot, length, upside diameter, middle diameter and bottom diameter of Lonicerae Japonicae Flos. The content of neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, rutin, galuteolin,3,5-icaffeoylquinic acid and 4,5-dicaffeoylquinic acid were detected by HPLC. Correlation analysis, principal component analysis and cluster analysis were used by SPSS to analyze all index data,and the correlation of appearance characteristics and intrinsic active constituents was discussed.
  
  
  RESULTS
  The numbers of flower bud and blooming rate per 0. 5 g, contamination content and browning degree were principal component indexes. The length of flower bud showed a significant correlation with galuteolin content, and the browning degree and upside diameter showed a significant correlation with chlorogenic acid content.
  
  
  CONCLUSIONS
  Lonicerae Japonicae Flos commercial should be divided into four specification grades by sieved indexes.
