Embodiment 1
[0025] 1 Instruments and reagents
[0026] 1.1 Instrument: high performance liquid chromatography (Dionex Ultimate 3000); chromatographic column: ZORBAX Eclipse Plus C 18 , 4.6 mm × 250 mm, 5 μm.
[0027] 1.2 Test drug:
[0028] 1.2.1 Reference substances and reference medicinal materials: naringin (for content determination, China Institute for the Control of Pharmaceutical and Biological Products, batch number 110722-200309); new eriocitrin (Sigma-Alkrich company, batch number: 1326322, purity: 98.6% ); Rhodorin (Sigma-Alkrich company, batch number: 023H0743, purity: 99.0%); hesperidin hydrate (prepared by Guangzhou Modern Chinese Medicine Quality Research and Development Center, confirmed by UV, IR, MS, NMR spectrum, purity: 98.5%); prunin (ChromaDex, Canada, purity>98%); 7-(2''-α-rhamnosyl-6''-(3''''-hydroxy-3''''- Methylglutaryl)-β-D-glucosyl)naringenin (prepared by Guangzhou Modern Traditional Chinese Medicine Quality Research and Development Center, confirmed by UV,...

[0063] 1 Instruments and reagents
[0064] 1.1 Instrument: high performance liquid chromatography (Dionex Ultimate 3000); chromatographic column: ZORBAX Eclipse Plus C 18 , 4.6 mm × 250 mm, 5 μm.
[0065] 1.2 Test drug: 10 batches of the active part of Huajuhong or its capsules, developed and produced by Guangzhou Modern Chinese Medicine Quality Research and Development Center. The methanol used in the liquid chromatography in the experiment is chromatographically pure, the rest of the reagents used are analytically pure, and the water is ultrapure water.
[0066] 2. Method and Results
[0067] 2.1 Preparation of the test solution: Take 0.25g of the active part powder, accurately weigh it, put it in a 100ml measuring bottle, add an appropriate amount of methanol for ultrasonic treatment (power 360W, frequency 35kHz) for 15 minutes, add methanol to dilute to the mark, and shake well. Filter through a 0.45 μm microporous membrane as the test solution.

[0109] Sample detection: take the following different sources of the citrus red medicinal material to prepare the effective part or its preparation sample as the test sample test set, prepare the operation according to the method under "Preparation of the test sample solution", inject the sample, and detect the fingerprint. Using the "Chinese Medicine Chromatographic Fingerprint Similarity Evaluation System 2009 Edition" for evaluation, the results show that: Huazhou pomelo (produced in Guangdong) and the control fingerprint similarity is greater than 0.90; Shatian pomelo (produced in Guangxi), Meizhou pomelo (produced in Guangdong), The similarities between the three batches of test product solutions from pomelo (produced in Fujian) and the control fingerprints were all less than 0.90. The similarity results are shown in Table 19:
