title: [Determination of puerarin in xinmaitong oral liquid by HPLC].
abstract: OBJECTIVE
  To develop a method to determine the content of puerarin in Xinmaitong oral liquid.
  
  
  METHODS
  HPLC method was used. The separation was performed on Suntek kromasil C18 column with methanol-water containing 0.5% acetic acid (25:75) as a mobile phase and the wavelength of UV detector was 250 nm.
  
  
  RESULTS
  The linearity of puerarin was good and average recovery was 97.8%.
  
  
  CONCLUSIONS
  The method is simple, reliable and sensitive. It also shows good resolation. It can be used in quality control of Xinmaitong oral liquid.
