Abstract:
Objective To establish the HPLC fingerprint of Sanhuang Xiexin Decoction and provide a method to study the potential basis and the changing of the chemical component for it in different compati- bility.Methods An HPLC method was established with Shimadzu ODS column(150 mm?4.6 mm, 5?m),the mobile phase was methanol-water-0.1% phosphoric acid(0.01 mol/L potassium phosphate monobasic,pH 2.8)as gradient elution,the flow rate was 1.0 mL/min,and the detection wavelength was 260 nm.Through comparing and analyzing the relative retention time of this decoction and of its composi- tion which are positive and negative control fingerprints,the main chromatographic peak origins were con- firmed;The correlated chromatographic peaks were identified by contrasting chromatographic peak reten- tion time and adding reference substances to the sample.Results All tested samples contained the 32 common peaks,the relativity of them were analyzed and 11 peaks were indicated.The similarity of ten batches of samples exceeded 0.92.Conclusion This method shows sensitive and good repeatability,all of the contents are separated well.It is used to determine Sanhuang Xiexin Decoction and its relative prepara- tions.
