title: [Determination of hedychenone in Hedychium yunnanense].
abstract: OBJECTIVE
  To establish an HPLC method for determination of hedychenone in Hedychium yunnanense.
  
  
  METHODS
  C18 Chromatographic column was used, acetonitrile-water (9:1) as mobile phase, at flow rate of 1.0 mL x min(-1): The wavelength for detection was 235 nm.
  
  
  RESULTS
  The linear range of hedychenone was 5.92-29.6 microg x mL(-1)(r = 0.9999). The average recovery was 99.0%, RSD of precision was less than 2%.
  
  
  CONCLUSIONS
  The method is simple, effective and feasible, and can be used to evaluate the quality of the herb.
