[0023] In one embodiment, the preparation method of Cornus officinalis extract comprises the following steps: 1) Ultrasonic-microwave synergistic extraction: dry Cornus officinalis powder with a particle size of 150-420 μm and 50 wt % ~80 wt% ethanol solution is put into the cavity of ultrasonic-microwave synergistic extraction equipment for extraction; after the extraction is completed, cool down, use a 150-200 mesh screen to filter the extract to obtain a filtrate, and concentrate the filtrate to obtain a concentrate; 2 ) centrifugation: dissolving the concentrated solution in water with 2 to 3 times the mass of the concentrated solution, and centrifuging to obtain a supernatant; 3) column chromatography: passing the supernatant through a chromatographic column, first using 10wt% to 30 wt% ethanol or water for 2 to 6 times the column volume to elute impurities, and then 50 wt% to 70 wt% ethanol for 2 to 6 times the column volume to elute and collect the eluate; 4) Concentrati...
Embodiment 1
[0033] Accurately weigh 200g of Cornus officinalis, dry at 45°C, and crush it to a coarse powder with a particle size of 250μm, add 1.6kg of ethanol solution with a concentration of 70%, and conduct ultrasonic-microwave collaborative extraction for 15min, with ultrasonic power 50W, microwave power 300W, constant temperature 55 ℃, the extract was filtered through a 200-mesh sieve, and concentrated under reduced pressure until the relative density was 1.12 at 25°C to obtain a concentrated solution; the concentrated solution was dissolved in water with twice the quality of the concentrated solution, and centrifuged at a centrifugal speed of 4000rpm for 20 minutes to obtain Supernatant: The supernatant is dynamically adsorbed by polyamide resin, and the adsorption and deflow rate is 1BV / h. After adding the sample, first use 5 times the column volume of 20% ethanol to elute the impurities, and then use 4 times the column volume of 70% ethanol to elute the impurities. % ethanol eluti...

[0035]Accurately weigh 200g of Cornus officinalis, dry at 50°C, and crush it to a coarse powder with a particle size of 420μm, add 1.2kg of 50% ethanol solution, ultrasonic-microwave collaborative extraction for 25min, ultrasonic power 50W, microwave power 250W, constant temperature 60 ℃, the extract was filtered through a 200-mesh sieve, and concentrated under reduced pressure until the relative density was 1.15 at 25°C to obtain a concentrated solution; the concentrated solution was dissolved in water twice the quality of the concentrated solution, and centrifuged at a centrifugal speed of 6000rpm for 10 minutes to obtain Supernatant: the supernatant is dynamically adsorbed by AB-8 macroporous adsorption resin, the adsorption flow rate is 0.5BV / h, after the sample is loaded, first use 5 times the column volume of 20% ethanol to elute the impurities, and then use 4 times the column volume The volume of 80% ethanol was eluted, and the eluate was collected. The amount of AB-8 ma...
