title: [Determination of shionone in Radix Asteris by HPLC].
abstract: OBJECTIVE
  To determine the content of shionone in Radix Aster from several different locations and markets.
  
  
  METHODS
  The HPLC analysis was used to determine shionone directly, using Polaris C18 column and acetonitrile as the mobile phase with a flow rate of 1.0 mL.min-1, and the UV detection wavelength was 200 nm.
  
  
  CONCLUSIONS
  The content of shionone was from 0.06% to 0.18%, depending on different locations and markets.
