title: [Determination of linarin in Yuye Jiedu granule by RP-HPLC].
abstract: OBJECTIVE
  To determine the content of linarin in Yuye Jiedu granule.
  
  
  METHODS
  A HPLC method was developed. The chromatographic conditions are as follows Luna C18 column and acetonitrile-0.05 mol x L(-1) phosphate buffer-phosphoric acid (30:70:0.06) as mobil phase, detection wavelenth at 327 nm.
  
  
  RESULTS
  The linear range of linarin was 0.025-0.50 microg. The average recovery was 98.7% and RSD 2.7%.
  
  
  CONCLUSIONS
  The method is simple and accurate, with good repeatability, and can be used for determination of linarin in Yuye Jiedu granule.
