Embodiment 1
[0134] Example 1 Establishment of the method for preparing the test solution
[0135] 1.1 Selection of extraction solvent:
[0136] Get the Zhuangyaojianshen pill sample 5g of batch number C08047, grind finely, accurately weigh, place in the Erlenmeyer flask with stopper of 50ml, add 25ml methyl alcohol, 75% methanol (volume percent concentration), 50% methanol (volume percent concentration) respectively accurately percent concentration), 95% ethanol (volume percent concentration), 50% ethanol (volume percent concentration), after ultrasonication for 45 minutes, let cool to room temperature, weigh, and use extraction solvent to supplement the lost weight respectively, shake well , filter, and take the continued filtrate, that is, too.
[0137] Under the following chromatographic conditions, measure the test solution prepared by different extraction solvents respectively, and record the chromatogram of 0-150min:
[0138] Column: Phenomenex Luna 5uC 18 (2) 100A chromatograp...
Embodiment 2
[0152] Example 2 Establishment of Chromatographic Conditions
[0153] 2.1 Determination of mobile phase
[0154] According to the preferred preparation method of the test solution in Example 1, about 5 g of the sample of batch number C08047 was taken to prepare the test solution. The column temperature is 30°C, the injection volume is 10 μl, the flow rate is 1ml / min, and the detection wavelength is 230nm. ), acetonitrile (A)-methanol (B)-water (C) and acetonitrile (A)-methanol (B)-0.1% phosphoric acid aqueous solution (C) are mobile phases, gradient elution, elution procedure is shown in Table 1. The elution time is 150min, and the chromatogram is recorded. Chromatogram see figure 2 .
[0155] The results showed that acetonitrile-methanol-0.1% phosphoric acid aqueous solution was the mobile phase, the baseline was relatively stable and the separation effect was the best. Therefore, acetonitrile-methanol-0.1% phosphoric acid aqueous solution was selected as the mobile p...
Embodiment 3
[0160] Example 3 Composition testing of Zhuangyaojianshen pills
[0161] 1. Column: Phenomenex Luna 5u C 18 (2) 100A chromatographic column (250×4.6mm, 5μm);
[0162] 2. Mobile phase: Acetonitrile-methanol-0.1% phosphoric acid aqueous solution is the mobile phase, and the gradient elution program is shown in Table 1;
[0163] 3. Flow rate: 1.0ml / min;
[0164] 4. Detection wavelength: 230nm;
[0165] 5. Column temperature: 30°C;
[0166] 6. the preparation of need testing solution: prepare according to the preferred method of embodiment 1;
[0167] 7. Preparation of reference solution: Precisely weigh protocatechuic acid, protocatechualdehyde, privetin, schizandrin A and (2′S)-schisandrin reference substance, and add methanol to prepare The concentration is a mixture of protocatechuic acid 120 μg / ml, protocatechualdehyde 130 μg / ml, privetin 140 μg / ml, Japanese Schizandrin A 40 μg / ml and (2′S)-Schisandra lignin 30 μg / ml Reference substance solution, to obtain;
