[0014] A preparation method of a drug raw material with hypnotic effect, comprising the following steps:
[0015] Step 1. Crush the roots, leaves, stems, flowers or the whole plant of Sunflower sunflower, add deionized water 10 times its mass and soak for 48 hours, filter with Buchner funnel, and collect the filtrate; Soak in water and repeat suction filtration 4 to 5 times; mix the filtrate obtained by suction filtration after multiple extractions to obtain mixed solution A, and set aside;
[0016] Step 2: After extracting the mixed solution A of the goldenflower sunflower material, the remaining material is vacuum-dried at low temperature, and then added to ethanol with 10 times its mass to soak for 24 hours for extraction, suction filtration through a Buchner funnel, and the filtrate is collected; Ethanol is recovered by pressure distillation; the recovered ethanol is added to the filter residue obtained by suction filtration to soak for extraction, the extraction is repeat...
