Embodiment 1
[0068] Chromatographic conditions: Thermo Acclaim TM 120 C18 column, 4.6mm×250mm, 5μm; mobile phase: A is pure water, B is acetonitrile; elution gradient: 0~5min, 5%B; 5~40min, 5%~35%B; 40~60min, 35%-95% B; detection wavelength: 254nm; column temperature: 30°C; flow rate: 1ml / min; injection volume: 10μL. Regarding the detection wavelength, the DAD full-wavelength scanning method is adopted, and a wavelength of 254nm with relatively obvious peak areas is selected. See the full-wavelength spectrum figure 1 and figure 2 .
[0069] Preparation of the test solution: Take an appropriate amount of 10 batches of hemostatic menstruation regulating granule samples (S1~S10 samples), pulverize them, take about 2.5g, weigh them accurately, add 20mL of methanol to a 25mL Erlenmeyer flask, and weigh them , after ultrasonic extraction for 30min, let it cool, make up the lost mass with methanol, shake well and let it stand, take the supernatant and pass it through a 0.22μm microporous mem...
Embodiment 2~5
[0110] The method of embodiment 2~5 is substantially the same as embodiment 1, and difference only is that when preparing need testing solution, solvent is respectively water, 30% volume percent methanol aqueous solution, 50% volume percent methanol aqueous solution and 80% volume percent methanol aqueous solution, Chromatographic results such as Figure 9 Shown, wherein A is embodiment 1, B is embodiment 5, C is embodiment 4, D is embodiment 3, E is embodiment 2.
Embodiment 6~8
[0112] The method of embodiment 6~8 is basically the same as embodiment 1, and difference only is that detection wavelength is respectively 210nm, 230nm and 270nm, and chromatographic result is as follows Figure 10 shown.
