Embodiment Construction
[0017] (1) Screening of solvent extracts of Radix Astragali and Cimicifuga to scavenge DPPH free radicals synergistically: Astragalus powder was extracted with ethanol with a volume fraction of 85% to 95% under reflux, and then concentrated to extract by rotary evaporation. Add deionized water of the same quality as the extract to make a suspension, place it in a separatory funnel, and sequentially extract it step by step with petroleum ether, chloroform, ethyl acetate, and n-butanol, and collect the solvent extracts and concentrate them into the extract Finally, the petroleum ether extract, chloroform extract, ethyl acetate extract and n-butanol extract of Astragalus were obtained respectively. Cimicifuga medicinal powder is also extracted and extracted by the above method to obtain Cimicifuga petroleum ether extract, chloroform extract, ethyl acetate extract and n-butanol extract. Through the determination of the DPPH free radical scavenging ability of the 4 extracts of Astr...
