Objective:A HPLC method for determination of andrographolide's content in andrographolide-resin complexes was studied.Method:Hypersil C18 column was used with methanol-water(55∶45) as the mobile and the detection wavelength was set at 225 nm.Results:linear in a range of 0.0956~0.956 μg the regression equation for andrographolide was Y=230.4X+47.264 with r=0.999 4.The average recovery was 99.99% and the RSD was 0.88%.Conclusion:The method is reliable and reproducible.It may be used for the determ ination of andrographolide in resin complexes of andrographolide ion-exchange resin.
