Abstract:Objective:To establish a method of HPLC fingerprinting and to analyze the quality of Cimicifuga heracleifolia Kom.in different areas.Methods:The column was a GL Sciences Inertsustain AQ-C18 column(250 mm×4.6 mm,5 μm).The mobile phase was acetonitrile-0.1% phosphoric acid solution.The column temperature was 30 ℃,the flow rate was 1.0 mL·min-1 and the detection wavelength was 317 nm.Ten peaks were extracted as the common peaks of 15 batches of samples.The similarity evaluation,cluster analysis and principal component analysis were used to compare and analyze 15 batches of samples.Results:Ten peaks were extracted as the common peaks of 15 batches of samples.the similarity was 0.80 or more.15 batches of samples were divided into two categories,and the guality in Liaoning producing areas were better.Conclusion:The method is simple and reliable,and can be used for quality control and evaluation of Cimicifuga heracleifolia Kom.in different areas.The quality of Cimicifuga heracleifolia Kom. in Liaoning producing areas are best and from different places in the same producing areas are different. |
