White paeony root fingerprint detection method

The invention discloses a white paeony root fingerprint detection method which includes the steps: 1 preparing white paeony root test solution; 2 preparing mixed reference solution; 3 precisely sucking the test solution and the mixed reference solution, injecting the solution into a high-performance liquid chromatograph and recording a chromatogram; 4 leading out a white paeony root fingerprint instrument obtained in the step 3, leading the chromatogram into a traditional Chinese medicine chromatographic fingerprint similarity evaluation system, selecting chromatographic peaks of chromatogramsof white paeony roots in different batches as common peaks, generating the reference fingerprint of the white paeony roots by an average computing method, and calculating relative retention time andrelative peak area of the common peaks. The white paeony root fingerprint detection method is good in stability, high in precision, good in repeatability and capable of comprehensively and objectivelyrepresenting the quality o
