title: [Quantification of isopimpinellin in root of Toddalia asiatica by HPLC].
abstract: OBJECTIVE
  To determine the content of isopimpinellin in root of Toddalia asiatica.
  
  
  METHODS
  A HPLC method was set up. Using Hypersil C18 column and methanol-water (70:30) as mobile phase, with the detection wavelength at 306 nm.
  
  
  RESULTS
  The linear range of isopimpinellin was 0.004 20 approximately 0.420 microg. The average recovery was 99.7% and the RSD 2.8%.
  
  
  CONCLUSIONS
  The method is simple and accurate, with good reproducibility, and can be used as a quantitative analysis method for isopimpinellin.
