ABSTRACT
Objective To establish the fingerprint chromatogram of Buzhong Yiqi Decoction(BYD) by multiple wavelength method,and to analyze the substance of formulas as a whole.Methods HPLC-PDA method was adopted.The chromatographic conditions were as followsHypersil ODS2 analytical column,the mobile phase consisting of 0.05 %phosphate acid and acetonitrile with gradient elution,detecting wavelength at 254 and 280 nm,the flow rate being 1.0 mL/min and the temperature of the column at 30 ℃.Results The methodological results were good.The results of dual-wavelength fingerprint chromatogram showed the all-around information of the fingerprints at 254 and 280 nm.The similarity of 10 batches of BuzhongYiqi Decoction was over 0.98.Conclusion Dual-wavelength fingerprint chromatogram can realize the analysis of a formulas as a whole,which supplies references for improving the quality control of BuzhongYiqi Decoction.
