title: [Study on RP-HPLC fingerprint of compound hongcao injection].
abstract: OBJECTIVE
  To establish the fingerprint detecting standard of Compound Hongcao Injection by reversed phase high performance liquid chromatography.
  
  
  METHODS
  The chromatographic conditions were as follows: an Inersil-ODS-3 column was used; the mobile phases (acetontrile and 0.1% phosphoric acid) with gradient elution; the flow rate 1.0 mL x min(-1) and the UV absorbance detection at 300 nm.
  
  
  RESULTS
  Under the same selected chromatographic conditions, the HPLC fingerprints of raw drugs and their intermediate, finished products were obtained with good separation and correlation according to the technical requirements of fingerprint on Injection of Chinese traditional medicine.
  
  
  CONCLUSIONS
  17 common peaks as well as their retention times and peak area ratios on HPLC fingerprint can be used as the important parameters of the quality control for Compound Hongcao Injection.
