Fingerprint spectrum construction method of Xinsunning capsule and fingerprint spectrum

The invention provides a fingerprint spectrum construction method of a Xinsunning capsule and a fingerprint spectrum, and the fingerprint spectrum construction method comprises the following steps: S1, taking different batches of Xinsunning capsule contents, adding a methanol aqueous solution, and carrying out ultrasonic extraction to obtain a test solution; s2, injecting the test solution into a high performance liquid chromatograph, carrying out gradient elution, carrying out chromatographic analysis, and recording a chromatogram map for 0-140 minutes; s3, importing the chromatogram into a traditional Chinese medicine chromatographic fingerprint spectrum similarity evaluation system, and processing to obtain a fingerprint spectrum; and S4, carrying out mass spectrometry on the test solution, and determining the chemical components of the chromatographic peak in the fingerprint spectrum according to the mass spectrometry result. The detection method for the fingerprint spectrum of the Xinsunning capsule has
