Embodiment 1

[0044] Example 1 Optimization of chromatographic conditions (taking Shengmaiyin (Dangshen Fang) as an example)

[0045] 1. Selection of detection wavelength

[0046] The liquid chromatograms ( figure 1 ), the preparation method of the test solution is: accurately pipette 920 μL of Shengmaiyin (Dangshen Fang) sample, add 80 μL of acetonitrile, centrifuge at high speed for 10 minutes (speed 13000 rpm), take the supernatant, filter it with a 0.45 μm microporous membrane, That is, the test solution was obtained. The chromatographic conditions are: chromatographic column: Agilent Extend C18 column (4.6mm×250mm, 5μm); mobile phase: A is acetonitrile, B is 0.1% formic acid aqueous solution, and the gradient elution is set according to the elution program in the table below; flow rate: 1.0mL / min; column temperature: 25°C; injection volume: 10μL.

Abstract

The invention discloses a test method for a pulse-activating preparation adopting pilose asiabell root, which can be used for measuring contents of 5-hydroxymethyl furfural, protocatechuic acid, lobetyolin and schizandrin in the pulse-activating preparation. The method comprises the steps of preparing a sample to be tested into a test product solution, obtaining the high performance liquid chromatogram of the test product solution through high performance liquid chromatographic detection, and then calculating according to standard curvilinear equations prepared through all comparison products to obtain the contents of 5-hydroxymethyl furfural, protocatechuic acid, lobetyolin and schizandrin in the pulse-activating preparation. The test method is high repeatability and stability, and is simple and convenient in operation. The contents of the four compounds are measured through one chromatography condition at the same time, the quality evaluation level of the pulse-activating preparation is improved, and meanwhile a certain basis can be provided for the identification on pilose asiabell root and Chinese magnoliavine fruit in crude medicine.
