Abstract

A fingerprint spectrum construction method for Xihuang capsules and a fingerprint spectrum includes: S1: taking contents of a Xihuang capsule, adding a methanol-chloroform-phosphoric acid solution, and carrying out ultrasonic extraction to obtain a Xihuang capsule test solution; S2: dissolving cholic acid, hyodeoxycholic acid, deoxycholic acid, bilirubin, muscone, and myrrhone in ethanol to obtain a mixed standard solution 1; dissolving quassin, 11-carbonyl-β-boswellic acid, 11-carbonyl-β-acetyl-boswellic acid, acetyl-11α-methoxy-β-boswellic acid, and sandaracopimaric acid in methanol to obtain a mixed standard solution 2; S3: respectively carrying out chromatography on the Xihuang capsule test solution and the mixed standard solutions 1 and 2, and recording corresponding chromatograms; and S4: constructing a fingerprint spectrum of the Xihuang capsule according to the chromatogram of the Xihuang capsule test solution and the chromatograms of the mixed standard solutions 1 and 2. The method can accurately, clearly and objectively evaluate the quality of Xihuang capsules.
