Embodiment 1
[0025] Example 1 Screening of the Fingerprint Construction Method of Qizao Oral Liquid
[0026] 1. Experimental materials
[0027] The 10 batches of Qizao oral liquid used in the experiment were provided by Zhongshan Hengsheng Pharmaceutical (batch numbers: 20130901, 20130902, 20130903, 20131001, 20131002, 20131003, 20131101, 20131102, 20131103, 20131104).
[0028] 2. Instrument
[0029] High-performance liquid chromatograph: Waters 2695 high-performance liquid chromatograph (American waters technology company); Quaternary pump, diode array detector (PAD2998), automatic sampler, Empower chromatographic workstation. Column: SHISEIDO-Capcell PAK-C 18 Chromatographic column (4.6mm×250mm, 5μm); balance: one-thousandth balance (Swiss Mettler ME203E), one-thousandth balance (Swiss Mettler ME204), one-hundred-thousandth balance (Swiss Mettler MS105); Ultrasonic generator (Kunshan Ultrasonic KQ-700DE40KHz280W); Ultrapure water system: Millipore, USA. Methanol, n-butanol, ethyl ace...

[0085] 7. Establishment and Analysis of Standard Fingerprints
[0086] (1) Collecting fingerprints
[0087] Take 10 batches of Qizao oral liquid and prepare it into a test solution respectively, and analyze it according to the chromatographic conditions determined in Example 1. Take formononetin as a reference peak, and record the fingerprints, see image 3 .
[0088] (2) Establishment of common patterns and determination of similarity
[0089] The fingerprints of 10 batches of Qizao oral liquid samples were imported into "Zhongzhi Pharmaceutical Group Traditional Chinese Medicine Fingerprint Database Software" to generate the common pattern of Qizao oral liquid fingerprints by the median method. A total of 12 common peaks were calibrated, and the common pattern was calculated. Compared with the reference substance, peak No. 2 was identified as protocatechuic acid; Peak No. 4 was Verbasidone glucoside; Peak No. 6 was Formononetin; Peak No. 9 was Verbasidone; Peak No. 10 For...
