Abstract: Objective To establish a HPLC method for determination of three active components in Shuanghua Caoshanhu Hanpian.Methods Agilent TC-C18 (4.6 mm × 250 mm,5 μm) column was used.The mobile phase was acetonitrile-water containing 0.2％ phosphoric acid with gradient elution mode at a flow rate of 1.0 mL· min-1,the column temperature was 30 ℃,the detection wavelength was 327 mn (0-10 min) for chlorogenic acid,342 nm (10-35 min) for isofraxidin and msmarinic acid.Results Chlorogenic acid had a good linearity in the range of 0.052-0.939 μg (r =0.999 8,n =6),the average recovery was 99.23％ with RSD of 1.4％ (n =9).Isofraxidin had a good linearity in the range of 0.004-0.077 μg (r =0.999 8,n =6),the average recovery was 100.33 ％ with RSD of 1.8 ％ (n =9).Rosmarinic acid had a good linearity in the range of 0.012-0.213 μg (r =0.999 9,n =6),the average recovery was 99.42％ with RSD of 1.4％ (n =9).Conclusion The method is simple,accurate and reliable.It can be used to determine chlorogenic acid,isofraxidin and rosmarinic acid in Shuanghua Caoshanhu hanpian at the same chromatogram condition.
