Embodiment 1
[0056] The optimization of the chromatographic separation conditions of the Shenqi hypoglycemic preparation includes the following steps:
[0057] The effect of different elution gradients on the separation of chemical components of the test solution of Shenqi hypoglycemic preparation was investigated.
[0058] (1) Chromatographic column: Agilent ZORBAX SB-Aq C18 column (4.6 × 250mm i.d., 5 μm); mobile phase: acetonitrile is used as mobile phase A, and 0.1% formic acid aqueous solution is used as mobile phase B; the elution method is : Linear gradient elution, see Table 1 for elution program 1; column temperature: 30°C; flow rate: 1.0mL / min; detection wavelength: 203nm. The obtained liquid chromatogram is shown in the appendix figure 1 , it can be seen from the figure that this elution procedure cannot completely elute the components in Shenqi Jiangtang Granules from the chromatographic column.
