Embodiment 1
[0022] a. Preparation process of traditional Chinese medicine: take 2000g of Rosa thorn fruit, add 10 times the amount of 70% ethanol to reflux for extraction for 5 hours, filter, and the filtrate for later use; add water to the residue and decoct twice, the first time for 4 hours, the second time for 2 hours, filter, Combine the filtrates, recover ethanol, concentrate to a clear paste with a relative density of 1.14-1.20 (60°C), add distilled water to disperse to a concentration of 0.025-0.035 g / mL (equivalent to the original drug), and adjust the pH of the liquid to 2.0-4.0 , after 30 min of D-101 macroporous adsorption resin, the adsorption rate is 1 BV / h, after adsorption, it is eluted with 3 BV of distilled water, and then 3 BV of 70% ethanol is used for elution at a flow rate of 1 BV / h. Collect the eluate, concentrate, dry in vacuum to form a dry paste, and crush the dry paste into fine powder;
