Objective To establish the HPLC fingerprint for the quality control of Yanhuanglian Injections.Methods HPLC Chromatography method was used.The conditions included a Shim-pack CLC-ODS column(250 mm?6.0 mm,5 ?m),the gredient elution was adopted with acetonitrile-buffer solution(1∶1),the detection wavelength was at 285 nm,and the flow rate was 1.0 mL/min.The Operating Standard of Similarty Evaluation System for Chromatographic Fingerprint of Chinese Materia Medica(Version 2004A)was used to calculate.Results Similarity of 13 batches of injections was over 0.95,the fingerprint of Yanhuanglian Injections was established,and 12 common peaks were indicated.Conclusion This method can be applied to the quality control of Yanhuanglian Injections.
