Embodiment 1
[0046] Example 1 : Citrus aurantium fine powder 600g, extract 4 times with 95% ethanol (crude drug: solvent weight ratio is 1: 6; 1: 4; 1: 4; 1: 4), merge extracts, reclaim ethanol to no alcohol smell, add Distill water to 600ml, and extract the aqueous solution with petroleum ether, ethyl acetate, and n-butanol successively for 6 times, 200ml each time. After concentration of n-butanol extraction part, 90g was obtained, put on D101 type macroporous resin column, eluted with water, 25% ethanol, 50% ethanol, 95% ethanol in sequence, and the 50% ethanol eluted part was concentrated and dried to obtain more than 20% Hesperidin and Naringin mixed total glycosides (55g).
Embodiment 2
[0047] Example 2: 600g of Citrus aurantii fine powder, extracted 3 times with 70% ethanol (the weight ratio of crude drug:solvent is 1:8; 1:6; 1:6), combined the extracts, recovered the ethanol until it had no alcohol smell, and added distilled water to 600ml , and the aqueous solution was sequentially extracted 4 times with petroleum ether, ethyl acetate and n-butanol, 300ml each time. The n-butanol extraction part was concentrated and dried to obtain 82g, which was loaded on a D101 macroporous resin column, and eluted with water, 25% ethanol, 50% ethanol, and 95% ethanol in sequence, and the 50% ethanol eluted part was concentrated and dried to obtain 20% The above hesperidin and naringin (47g).
