Embodiment 1
[0021] Take red peanut medicine, add water 10-15 times its weight, boil for 90 minutes, filter, concentrate the filtrate under reduced pressure to a relative density of 1.12, add ethanol to 80% alcohol content, precipitate at 4°C for 24 hours, filter, filtrate filtrate Concentrate to a relative density of 1.15, add 10 times the amount of water, precipitate at 4°C for 12 hours, centrifuge, take the supernatant, absorb it with 30% by weight D101 macroporous adsorption resin, eluate 2 columns with deionized water Volume, and then continue to elute with deionized water for 4 column volumes, collect the eluate, absorb it with 5% by weight of polyamide, first wash with deionized water until colorless, and then wash with 95% ethanol for 8 column volumes , Collect the eluate, concentrate on a rotary evaporator to remove ethanol, freeze-dry to obtain safflower yellow, and measure the content of safflower glycoside A in 85%.
Embodiment 2
[0023] Take red peanut medicine, add water 10-15 times its weight, boil for 70 minutes, filter, and concentrate the filtrate under reduced pressure to a relative density of 1.20, add ethanol to 80% alcohol content, precipitate at 4°C for 24 hours, filter, and filtrate filtrate Concentrate to a relative density of 1.10, add 10 times the amount of water, precipitate at 4°C for 24 hours, centrifuge, take the supernatant, absorb it with 40% by weight D101 macroporous adsorption resin, eluate 3 columns with deionized water Volume, and then continue to elute with deionized water for 5 column volumes, collect the eluate, absorb it with 10% by weight of polyamide, first wash with deionized water until colorless, and then wash with 95% ethanol for 8 column volumes , Collect the eluate, concentrate on a rotary evaporator to remove ethanol, freeze-dry to obtain safflower yellow, and the content of safflower glycoside A is determined to be 90%.
Embodiment 3
[0025] Take red peanut medicine, add water 10-15 times its weight, boil for 50 minutes, filter, concentrate the filtrate under reduced pressure to a relative density of 1.25, add ethanol to 80% alcohol content, precipitate at 4°C for 24 hours, filter, filtrate filtrate Concentrate to a relative density of 1.20, add 10 times the amount of water, precipitate at 4°C for 24 hours, centrifuge, take the supernatant, absorb it with 40% by weight D101 macroporous adsorption resin, and eluate 3 columns with deionized water Volume, and then continue to elute with deionized water for 5 column volumes, collect the eluate, absorb it with 10% by weight of polyamide, first wash with deionized water until colorless, and then wash with 95% ethanol for 8 column volumes , Collect the eluate, concentrate on a rotary evaporator to remove the ethanol, freeze-dry to obtain safflower yellow, and the content of safflower glycoside A is determined to be 98%.
