Embodiment 1
[0033] Weigh 100 grams of Radix Paeoniae Rubra powder with a particle size of 24 mesh, heat it in 1200 mL of deionized water under reflux at 80°C for 1 hour, then concentrate it at 70°C to a water content of 5%, to obtain the reference substance.
Embodiment 2
[0035] Weigh 100 grams of Radix Paeoniae Rubra powder with a particle size of 24 mesh, soak it in 1200 mL of 50% ethanol for 1 hour, and obtain the first product 1. The first product was heated under reflux in a water bath at 80° C. for 0.5 h to obtain the second product 1 . The second product was concentrated to a water content of 5% at 170°C to obtain the third product 1. The third product 1 was dissolved in 200 mL of deionized water to obtain the fourth product 1. The fourth product 1 was centrifuged at 3000 r / min for 30 min, and the supernatant was collected to obtain the fifth product 1. Get 100mL of the fifth product 1 to flow through the diameter-to-height ratio of 1:9, after the volume is absorbed by the D101 type macroporous resin chromatography column of 100mL, rinse the macroporous resin with 400mL deionized water, and finally use 300mL volume concentration of 65% Ethanol solution was used for elution, and the eluate was collected to obtain product 1. The flow ra...
