Abstract：Objective To establish a qualitative and quantitative control method for Radix Paeoniae.Methods The characteristic atlas of Radix Paeoniae was established by HPLC,and the chemical constituents of common peaks were identi-fied by mass spectrometry.The authenticity of Radix Paeoniae was determined by the similarity between the characteristic peaks of Radix Paeoniae and those of Radix Paeoniae.The reference material"Paeoniflorin"was accurately quantified,and the relative content of each characteristic peak in different batches of test products was calculated with"Paeoniflorin".Re-sults The quality-quantity analysis method of Radix Paeoniae met the requirements of methodology investigation.9 chrom-atographic peaks were identified and 5 chemical components were identified.The similarity between the tested herbs and the control herbs was greater than 0.900.The lower limit of relative content of chemical components of characteristic peak of Ra-dix Paeoniae was specified.Conclusion This method can judge the authenticity of Radix Paeoniae clearly and quickly,and can provide reference for the quality control of Radix Paeoniae.
