Abstract

[Objective] The aim was to determine the content of magnolol in Qianbei Magnolia officinalis by HPLC method.[Method] A Diamonsil C18 column was used with mobile phase of methanol-water(78∶22),the detection wavelength was 294 nm,the flow rate was 1.0 ml/min,the column temperature was 25 ℃.[Result] The magnolol good liner range was within 0.627 2-1.164 8 ug,r=0.999 4.The average recovery was 98.56% and RSD was 0.33%.[Conclusion] The method is simple,sensitive and accurate.
