Detection method for fingerprint spectrum of Qingtong capsule, fingerprint spectrum and quality detection method

The invention relates to a detection method of a fingerprint spectrum of a Qingtong capsule, a fingerprint spectrum and a quality detection method, and the detection method of the fingerprint spectrum comprises the following steps: preparing a reference substance solution and a test solution, and respectively injecting the reference substance solution and the test solution into a high performance liquid chromatograph for detection. The fingerprint spectrum of the Qingtong capsule obtained by the invention can comprehensively reflect the types and the quantity of chemical components contained in the Qingtong capsule, so that the quality of the Qingtong capsule is integrally described and evaluated, the chemical components related to 12 characteristic peaks are relatively more, and five medicine flavors of the Qingtong capsule are covered; meanwhile, the base line of each characteristic peak is relatively stable, and the separation degree, the peak shape and the column efficiency are relatively good; the whole
