| titleOfInvention | A kind of celery seed extract and preparation method thereof |
| abstract | The invention discloses a celery seed extract and a preparation method thereof. The preparation method comprises the following steps: (1) taking celery seed, pulverizing and sieving, adding 3 to 5% diatomite of the mass of the medicinal material, adding 8 to 12 times the amount of 50 to 60% ethanol for reflux extraction, suction filtration to combine the filtrate, and concentration under reduced pressure to obtain the extract; (2) take the extract, add ethyl acetate:n-butanol=2:8 or 1:9 Extract, stir, leave standstill, extract, collect organic layer, concentrate under reduced pressure, dry to obtain total flavonoid extract; (3) get acidic alumina, the weight of acidic alumina: the weight of total flavonoid extract is 1: 10～ 20. Pack the column and activate petroleum ether; take the total flavonoid extract, dissolve it completely in ethanol, add acidic alumina to mix the sample, evaporate to dryness to remove ethanol, load the sample, first elute with petroleum ether, then elute with ethanol, and collect ethanol The effluent was dried and tested to obtain celery seed extract. The invention can effectively increase the total flavonoid content of the celery seed, so that the total flavonoid content of the celery seed reaches more than 80%. |
