title: [The quality standard study on Hugan qingzhi tablets].
abstract: OBJECTIVE
  To develop a method of quality control for Hugan qingzhi tablets.
  
  
  METHODS
  Fructus Crataegi, Rhizoma Alismatis and Radix Notoginseng were identified by TLC. HPLC was used for the determination of ursolic acid in Hugan qingzhi tablets.
  
  
  RESULTS
  The chromatographic spots were identified without the interference of negative control. Ursolic acid had a good linearity over the concentration range of 40-200 microg/mL (r = 1.000). The average recoveries was 99.05% with relatively standard deviations of 1.3%.
  
  
  CONCLUSIONS
  This method is reliable, accurate and specific and can be used for the quality control of Hugan qingzhi tablets.
