preparation example 1
[0037] Preparation Example 1: Preparation of Sophora flavescens extract
[0038] Sophora flavescens was ground into powder (20-40 mesh), sieved, soaked in 60% ethanol for 2 hours, heated and refluxed for 1.5 hours, extracted twice, and the extracts were combined; the extracts were concentrated until no alcohol smell, Add 0.5% hydrochloric acid to dilute until the pH value of the solution is 1.5, filter out the insoluble matter, extract the filtrate 3 times with chloroform, adjust the pH value of the aqueous phase to 10 with ammonia water, extract 3 times with chloroform, combine the organic layers, evaporate The solvent is removed and dried to obtain Sophora flavescens extract. If not stated otherwise, this extract was used in the following experiments.
