Embodiment 1
[0026] Embodiment 1: Screening of chromatographic conditions
[0027] (1) Screen different chromatographic columns to investigate the number of peaks, resolution and peak shape. (area normalization method, peaks below 0.05% are not counted)
[0028]
[0029] From the results, Agilent TC-C18 (250mm×4.6mm, 5um) had the most detection peaks and the best resolution. Agilent TC-C18 was selected to develop the HPLC characteristic fingerprint detection method for Agui Yangxue preparation.
[0030] (2) Screen different mobile phase salts to investigate the number of peaks, resolution and peak shape. Tested with Agilent TC-C18 (250mm×4.6mm, 5um) chromatographic column.
[0031] (area normalization method, peaks below 0.05% are not counted)
[0032]
[0033] From the results, the 30mmol / L triethylamine solution had the most detected peaks and the best resolution, and the 30mmol / L triethylamine solution was selected as the mobile phase salt for the HPLC characteristic fingerprin...
Embodiment 2
[0037] Example 2: Fingerprint Methodology Validation
[0038] 1. Instrument
[0039] Agilent1260 high performance liquid chromatography (Agilent, USA); PB-10 pH meter (Sartorius), BP-211D electronic analytical balance (Sartorius).
[0040] 2. Test solution
[0041] Acetonitrile (Tiandi, chromatographically pure), triethylamine (Chinese medicine, analytically pure), methanol (Tianjin Best Chemical, analytically pure), and water was Wahaha purified water.
[0042] 3. Reference substance
[0043] Paeoniflorin (batch number 110736-201842 China National Institutes for Food and Drug Control, content 97.4%)
[0044] 4. Sample
[0045] Agui Nourishing Blood Preparation (Lot No.: 180501, Kangpu Pharmaceutical Co., Ltd.)
[0046] 5. Chromatographic conditions: Octadecylsilane bonded silica gel as filler, acetonitrile as mobile phase A, acetonitrile-30mmol / L triethylamine (5:95) as mobile phase B, gradient elution, flow rate 1.0 ml·min-1, the column temperature is 35°C, the detecti...
Embodiment 3
[0060] Example 3 Common peaks and peak assignments
[0061] The 9 medicinal materials in the prescription of Agui Yangxue preparation were prepared separately according to the method of the above-mentioned Example 2, and the test solution was separately analyzed according to the above-mentioned chromatographic conditions, and the chromatograms of the Agui Yangxue preparation sample (180501) and each medicinal material were compared. Find peak assignments.
[0062] With reference to paeoniflorin reference substance, record the relative retention time of common peaks. There are 14 common peaks in the fingerprint. See Table 1 below, figure 2 .
