Embodiment 1

[0046] This example is the preparation of safflower yellow:

[0047] Wash and dry safflower plus 10 times the weight of 50% ethanol aqueous solution, extract three times in a water bath at 55°C, each extraction time is 30 minutes, combine the three extracts, concentrate the extract at 55°C under reduced pressure, and make The concentrated solution contains 0.5g of crude drug per milliliter, adjust the pH value to 3 with dilute hydrochloric acid, put it on the AB-8 macroporous resin column, let it stand for adsorption for 3 hours, wash the column with 7 times the column volume of distilled water with a pH of 3 to remove sugar, and then Wash the column with 7 times column volume of 30% ethanol aqueous solution for decolorization, discard the first 1 times column volume of 30% ethanol eluate, collect the remaining eluate, concentrate it under reduced pressure, and spray dry the concentrated solution. That is, safflower yellow pigment.

Embodiment 2

[0049] This example is the preparation of safflower yellow:

[0050] Add 8 times the weight of 50% ethanol aqueous solution to the washed and dried safflower, extract twice in a water bath at 60°C, each extraction time is 20 minutes, combine the extracts, concentrate the extracts under reduced pressure at 35°C, and make The concentrated solution contains 0.5g of crude drug per milliliter, adjust the pH value to 3 with dilute hydrochloric acid, put it on the AB-8 macroporous resin column, let it stand for adsorption for 2 hours, wash the column with 8 times the column volume of distilled water with a pH of 3 to remove sugar, and then Wash the column with 8 times column volume of 30% ethanol aqueous solution for decolorization, discard the first 30% ethanol eluate of 1 column volume, collect the remaining eluate, concentrate it under reduced pressure, and spray dry the concentrated solution. That is, safflower yellow pigment.

Embodiment 3

[0052]This example is the preparation of safflower yellow:

[0053] Add 12 times the weight of washed and dried safflower to 50% ethanol aqueous solution, extract four times in a water bath at 50°C, each extraction time is 40 minutes, combine the four extracts, and concentrate the extract at 45°C under reduced pressure , so that the concentrated solution contains 0.5g of crude drug per milliliter, adjust the pH value to 3 with dilute hydrochloric acid, put it on the AB-8 macroporous resin column, let it stand for adsorption for 2.5 hours, wash the column with 6 times the column volume of distilled water with a pH of 3 to remove sugar , then wash the column with 6 times column volume of 30% ethanol aqueous solution for decolorization, discard the first 30% ethanol eluate of 1 column volume, collect the remaining eluate, concentrate it under reduced pressure, and spray the concentrate Dry to obtain safflower yellow.
