3 Terms and definitions

There are no terms and definitions that need to be defined in this document.

4 Principle

In the same analysis cycle, adjust the mobile phase ratio according to a certain time program to make the key components of the hawthorn leaf extract according to their respective appropriate The capacity factor achieves a good separation purpose. The external standard method corresponding to hyperoside was used for direct quantification, and the chromatographic column used was a reversed-phase C18 column. Ultraviolet light of hyperin Spectral measurement showed that the maximum absorption wavelength was 360nm, so 360nm was selected as the detection wavelength of hyperoside by high performance liquid chromatography.

5 Reagents and materials

Unless otherwise specified, only reagents of analytical purity and water that meet GB/T 6682 level 1 are used in the analysis. 5.1 Reagents 5.1.1 Methanol (CH3OH), chromatographically pure. 5.1.2 Glacial acetic acid (CH3COOH). 5.2 Standard products Hyperin standard product. purity ≥98%. 5.3 Standard stock solution of hyperoside Weigh.200mg (accurate to 0.001g) hyperoside standard substance in a 100mL brown volumetric flask, add methanol to dissolve and dilute to
