Embodiment 1
[0046] Embodiment 1 preparation method of celery seed flavonoids and coumarin compounds
[0047] 10 kg of dried celery seeds were extracted by percolation with 95% (V / V) ethanol, and 15 times the amount of percolation liquid was collected, and the extract was concentrated under reduced pressure at 55° C. to almost no ethanol to obtain a thick extract. Add 1 times the amount of water to the extract to dilute the suspension, and extract 3 times with one-third volume of petroleum ether (60-90°C) of the diluent, separate the petroleum ether and recover the petroleum ether extract of petroleum ether. The aqueous layer is extracted 4 times with one-third volume of ethyl acetate, separates ethyl acetate and reclaims ethyl acetate to obtain celery seed ethyl acetate extract, which mainly contains celery seed coumarin and flavonoids Compound components are represented by (CFE). The content of flavonoids in the extract is 55-65%, and the content of coumarins is 5-10%.
Embodiment 2
[0048] Embodiment 2 preparation method of celery seed flavonoids and coumarin compounds
[0049] 10 kg of dried celery seeds were extracted by percolation with 75% (V / V) ethanol, and 20 times the amount of percolation liquid was collected, and the extract was concentrated under reduced pressure at 55° C. to almost no ethanol to obtain a thick extract. Add 2 times the amount of water to the extract to dilute the suspension, then extract 2 times with 1 / 3 volume of petroleum ether (60-90°C) of the diluent, separate the petroleum ether and recover the petroleum ether extract of petroleum ether. The aqueous layer is extracted 4 times with one-third volume of ethyl acetate, separates ethyl acetate and reclaims ethyl acetate to obtain celery seed ethyl acetate extract, which mainly contains celery seed coumarin and flavonoids Compound components are represented by (CFE). The content of flavonoids in the extract is 55-65%, and the content of coumarins is 5-10%.
Embodiment 3
[0050] Embodiment 3 preparation method of celery seed flavonoids and coumarin compounds
[0051] 10 kg of dried celery seeds were heated and extracted with 4 times the amount of 95% (V / V) ethanol for 3 times, each heating for 1 hour; the extract was collected, concentrated under reduced pressure at 55°C until nearly free of ethanol, and a thick extract was obtained. Add 1 times the amount of water to the extract to dilute the suspension, and extract 3 times with one-third volume of petroleum ether (60-90°C) of the diluent, separate the petroleum ether and recover the petroleum ether extract of petroleum ether. The aqueous layer is extracted 4 times with one-third volume of ethyl acetate, separates ethyl acetate and reclaims ethyl acetate to obtain celery seed ethyl acetate extract, which mainly contains celery seed coumarin and flavonoids Compound components are represented by (CFE). The content of flavonoids in the extract is 55-65%, and the content of coumarins is 5-10%.
