title: Determination of L-sesamin and L-asarinin in Zanthoxylum(Roxb.) DC. by high performance liquid chromatography.
abstract: OBJECTIVE
  To establish a method for determining the content of L-sesamin and L-asarinin indifferent parts of Zanthoxylum(Roxb.)DC.
  
  
  METHODS
  High-performance liquid chromatography (HPLC) was utilized for this purpose with the column of HYPERSIL BDS C18 and the mobile phase containing acetonitrile and water (50:50), the detection wavelength being 287 nm.
  
  
  RESULTS
  The average recovery rates for L-sesamin and L-asarinin were 100.13% and 1.61% and their relative standard deviation (RSD) were 101.24% and 1.46% respectively.
  
  
  CONCLUSIONS
  The method can be used for the quality control of Zanthoxylum(Roxb.)DC, and the roots of this herb contains more L-sesamin and L-asarinin than its other parts do.
