Detailed Implementation

[0014] Example 1 A quality control method for a traditional Chinese medicine compound used for gastric ulcers, the method being as follows: S1. Preparation of mixed reference solution: Weigh out 2.0 mg each of the following reference standards: verbascoside, isoliquiritin, 1.0 mg of safflower flavonoid, 2.0 mg of gentianin, 2.0 mg of ternolactone, 2.0 mg of atractylodes lactone I, 2.0 mg of atractylodes lactone II, 1.0 mg of isohesperidin, 2.0 mg of tyrosine, 2.0 mg of atractylodes lactone III, 2.0 mg of cryptochlorogenic acid, and 2.0 mg of lycopene. Add anhydrous ethanol to each standard and bring the volume to 5 ml. Twelve reference solutions were obtained in mL volumetric flasks, namely, verbascoside reference solution, isoglycyrrhizin reference solution, cheronitin reference solution, styrosine reference solution, baicalein reference solution, baicalein reference solution, atractylodes lactone reference solution, atractylodes lactone I reference solution, atractylodes lactone II reference solution, isohexolone reference solution, tyrosine reference solution, atractylodes lactone III reference solution, cryptochlorogenic acid reference solution, and honeysuckle glycoside reference solution; Take 400 μL of each reference solution separately, mix them, and dilute to 10 mL in a volumetric flask with anhydrous ethanol to obtain a mixed reference solution; S2. Preparation of the test Chinese herbal medicine solution: The traditional Chinese medicine for gastric ulcers (1 g Aconitum carmichaelii, 1 g Codonopsis pilosula, 1 g dried ginger, 1 g licorice, and 1 g Atractylodes macrocephala) was soaked in distilled water at a ratio of 1 g: 10 mL for 30 min to ensure complete wetting. The mixture was then subjected to two reflux extractions: the first for 30 min and the second for 20 min. The extracts were combined, filtered through gauze, concentrated in a rotary evaporator at 70 °C, centrifuged at 10000 rpm for 10 min at 4 °C, evaporated to dryness at 70 °C, dissolved in anhydrous ethanol by sonication for 5 min, and diluted to a 10 mL volumetric flask to obtain the test herbal solution (Fuzi Lizhong Decoction). S3, Measurement: The mixed reference solution obtained in S1 and the test traditional Chinese medicine solution obtained in S2 were injected under the following conditions set for liquid chromatography-tandem mass spectrometry (UHPLC-MS detection): S301, Liquid Chromatography Conditions: A 50 mm × 2.1 mm Hypersil Gold column with a particle size of 1.9 μm was used; the column temperature was 30 °C; the mobile phase was methanol + water; the gradient elution conditions were: 0–6 min, methanol volume ratio of mobile phase 25%–80%; 6 min–7 min, methanol volume ratio of mobile phase 80%–95%; 7 min–8 min, methanol volume ratio of mobile phase 95%–100%; 8 min–9 min, methanol volume ratio of mobile phase 100%; the flow rate was 0.3 mL / min. S302, Mass Spectrometry Conditions: Scanning mode: Full-MS / DD-MS2, simultaneous acquisition of positive and negative ions; positive ion scanning range 100 m / z~1500 m / z, negative ion scanning range 100 m / z~1500 m / z; resolution 17500; capillary temperature: 300℃; spray voltage: 4.0 kV and -3.5 kV; sheath gas volumetric flow rate 35 L / h; S-lens voltage 50 V; S4, Judgment: A blank solvent was set as a control. Under the conditions of liquid chromatography described in S301 and mass spectrometry described in S302, the presence of corresponding chemical components in the tested Chinese medicine solution was determined based on the chromatographic retention time and the precise molecular weight of the mass spectrometer. The mixed reference solution obtained in S1 was diluted into 5 mass concentration gradients. The mass concentration of each chemical component was plotted on the x-axis and the peak area on the y-axis. Standard working curves for 12 chemical components were plotted. The tested Chinese medicine solution obtained in S2 was quantified using the standard working curves. The response values ​​of the chemical components in the tested Chinese medicine solution were within the linear range of the instrument detection. The method for determining whether the corresponding chemical components exist in the tested traditional Chinese medicine solution is as follows: the chromatographic retention time and precise molecular weight information of the chemical components in the tested traditional Chinese medicine solution should be consistent with the information of the corresponding components in the mixed reference solution, with an allowable deviation of less than ±2.5%. The contents of the chemical components contained in the traditional Chinese medicine were determined as follows: verbascoside, isoliquiritin, saflavin, styroside, chrysanthemum flavonoid, chrysanthemum lactone, atractylodes lactone I, atractylodes lactone II, isohesperidin, tyrosine, atractylodes lactone III, cryptochlorogenic acid, and honeysuckle glycoside.

[0015] Methodological investigation (1) Systematic investigation: The systematic investigation is to investigate whether there are chromatographic peaks in the anhydrous ethanol reagent that interfere with these 12 chemical components. First, the anhydrous ethanol and the mixed reference solution were filtered through a 0.22 μm microporous membrane and then detected by liquid chromatography-mass spectrometry.

[0016] (2) Examination of linear relationship: The examination of linear relationship uses the peak area as the ordinate (Y) and the concentration of each reference standard as the abscissa (X). The linear regression equation is calculated, and r is used as the expression. 2 >0.995 was used as the criterion for good linearity. First, the mixed reference solution was serially diluted by 10, 20, 50, 100, 200, 500, 1000, 2000, and 5000 times to prepare mixed reference solutions with 9 concentration gradients. All solutions were then filtered through a 0.22 μm microporous membrane and detected according to the conditions in step S3.

[0017] (3) Precision test: The precision test is based on RSD≤3% as the standard for good precision. After taking the mixed reference solution diluted 20 times, filter it through a 0.22 μm microporous membrane and inject it 6 times in a row, 2 μL each time. Calculate the RSD value of the peak area of ​​the Target-SIM extracted ion chromatogram of each reference in the 6 injections.

[0018] (4) Stability test: The stability test was based on RSD ≤ 3% as the criterion for good stability. One part of Fuzi Lizhong Decoction solution was filtered through a 0.22 μm microporous membrane and injected at 0, 4, 8, 16, 24 and 48 h respectively for analysis. Each injection was 2 μL, and the RSD value of the Target-SIM extracted ion chromatogram peak area of ​​Fuzi Lizhong Decoction was calculated for each of the 6 injections. (5) Repeatability test: The repeatability test is based on RSD≤3% as the criterion for good repeatability. Six parallel solutions of Fuzi Lizhong Decoction were prepared and filtered through a 0.22 μm microporous membrane. 2 μL of each solution was injected into the membrane, and the RSD value of the mass fraction of each component in the six tested traditional Chinese medicine solutions was calculated.

[0019] (6) Recovery test: Dilute the Fuzi Lizhong Decoction solution by 2 times and take 40 μL to obtain test solution 1; Take 40 μL of the mixed reference solution diluted 100 times to obtain test solution 2; Test solution 1 and test solution 2 are mixed to obtain test solution 3; All test solutions were filtered through a 0.22 μm microporous membrane, and 2 μL of each solution was injected. The mass concentrations (C1, C2, and C3) of each compound in test solutions 1, 2, and 3 were calculated based on the corresponding standard curves. The recovery rate was calculated as (C3 - C1) / C2, and the RSD of the recovery rate was also calculated. A recovery rate within the range of 98% to 102% was considered acceptable.

[0020] (7) Limit of detection (LOD) and limit of quantification (LLOQ): The LOD and LLOQ of the 12 components were determined by a relatively intuitive method. Two samples with known component contents were added near the low concentration point of the standard curve for detection. A baseline near the analyte peak was selected as a reference, and the signal-to-noise ratio (S / N) of the chromatographic peaks of the 12 chemical components was calculated. The sample concentrations with S / N≥3 and S / N≥10 were used as LOD and LLOQ, respectively.

[0021] Experimental results: Results of methodological investigation (1) Systematic evaluation: Ion chromatograms of verbascoside, isoliquiritin, saflavin, gentianin, chrysanthemum lactone, atractylodes lactone I, atractylodes lactone II, isohesperidin, tyrosine, atractylodes lactone III, cryptochlorogenic acid, and honeysuckle were extracted using anhydrous ethanol blank reagent. Figure 1 Extracts of verbascoside, isoliquiritin, saflavin, gentianin, chrysanthemum flavonoids, chrysanthemum lactone, atractylodes lactone I, atractylodes lactone II, isohesperidin, tyrosine, atractylodes lactone III, cryptochlorogenic acid, and honeysuckle glycoside ion chromatograms were obtained from a mixed standard solution.

This shows that anhydrous ethanol has no significant interference with the determination of the contents of these 12 compounds. Detailed chromatographic-mass spectrometric data for these 12 compounds are shown in Table 1.
