Embodiment 1
[0024] The establishment of embodiment 1 fingerprint
[0025] HPLC conditions: YMC J'sphere ODS-H80-C18 (4.6mm×250mm, 4μm), the mobile phase is acetonitrile (A)-mass percentage 0.5% phosphoric acid (B), gradient elution is: 0- 15min, 15%-21%A; 15-35min, 21%-26%A; 35-50min, 26%-34%A; 50-70min, 34%-61%A; 70-85min, 61%-75 %A; 85-90min, 75%-95%A; 90-100min, 95%-100%A, flow rate 1.0mL·min-1, column temperature 30℃, injection volume 30μL. The detection wavelength is 203nm, 270nm, and the volume percentage of acetonitrile in each time period of the total mobile phase in the above gradient elution process increases at a uniform speed. That is, the following table:
