title: [Determination of lobetyolin in root of Codonopsis tangshen from various cultivation areas by high-performance liquid chromatography].
abstract: OBJECTIVE
  To determine lobetyolin in the root of Codonopsis tangshen from the various cultivation areas.
  
  
  METHODS
  A Supelco Discovery C18 Column (4.6 mm x 250 mm, 5 microm) was used with acetonitrile-0.5% acetic acid in water (20:80) as the mobile phase and UV detection was at 268 nm.
  
  
  RESULTS
  Twenty-four batches of the samples were analyzed. The content of lobetyolin ranged from 0.0403-0.9667 mg x g(-1).
  
  
  CONCLUSIONS
  The method was simple, reproducible and reliable. It can be used to control the quality of C. tangshen.
