Embodiment 1
[0035]Preparation method: take citrus aurantium or citrus aurantium, cut into decoction pieces, add 10 times the volume of 35% ethanol to reflux extraction for 3 times, each time reflux extraction for 1.5 hours, filter; combine the filtrate, recover ethanol from the filtrate, and pass the aqueous solution through the processed AB-8 macroporous resin, eluted with water and 18% ethanol successively to remove impurities, then eluted with 37% ethanol and 0.5% sodium hydroxide, collected the 37% ethanol eluate, concentrated under reduced pressure to a relative density of about 1.22 (50 ℃) liquid extract, dried under reduced pressure (63 ℃), crushed, that is.
Embodiment 2
[0037] Preparation method: take Citrus aurantium or Fructus aurantium, cut into decoction pieces, add 6 times the volume of 56% ethanol to reflux extraction for 3 times, each time reflux extraction for 1 hour, and filter; combine the filtrate, recover ethanol from the filtrate, and pass the aqueous solution through the processed D101 macroporous resin, eluted with water and 16% ethanol in order to remove impurities, then eluted with 35% ethanol and 0.7% sodium hydroxide, collected 35% ethanol eluate, concentrated under reduced pressure to a relative density of about 1.20 (55°C) The liquid extract, dried under reduced pressure (60 ℃), crushed, that is.
Embodiment 3
[0039] Preparation method: take citrus aurantium or citrus aurantium, cut into decoction pieces, add 11 times the volume of 40% ethanol to reflux extraction twice, each time reflux extraction for 1 hour, filter; combine the filtrate, recover ethanol from the filtrate, and pass the aqueous solution through the processed D101 macroporous resin, eluted with water and 14% ethanol in turn to remove impurities, then eluted with 40% ethanol and 0.8% sodium hydroxide, collected 40% ethanol eluate, concentrated under reduced pressure to a relative density of about 1.23 (55°C) The liquid extract, dried under reduced pressure (65 ℃), crushed, that is.
