Embodiment 1
[0159] Take safflower medicinal powder, add 10 times of water, heat to 100°C, keep warm for 30 minutes, filter and cool the filtrate. Add 10 times water to the filter residue, heat to 100°C, keep warm for 20 minutes, filter, cool, and combine the filtrate to stand for 4 hours. After the supernatant is centrifuged, use an ultrafiltration membrane to remove macromolecular impurities. Adsorbent resin D 4020 Column adsorption, deionized water elution, collected eluate, concentrated by membrane, concentrated solution was subjected to molecular sieve chromatography, and the loading amount was 6% of the volume of the chromatographic column. Elute with distilled water, collect the eluate and concentrate, and freeze-dry the concentrate to obtain safflower yellow; determined by high performance liquid chromatography, the content of safflower yellow is 88.6%. See attached figure 1 .
Embodiment 2
[0161] Take safflower medicinal powder, add 10 times of water, heat to 100°C, keep warm for 30 minutes, filter and cool the filtrate. Add 10 times water to the filter residue, heat to 100°C, keep warm for 20 minutes, filter, cool, and combine the filtrate to stand for 4 hours. After the supernatant is centrifuged, use an ultrafiltration membrane to remove macromolecular impurities. Adsorbent resin D 4020 Column adsorption, deionized water elution, collect the eluate, concentrate through the membrane, the concentrated solution is subjected to molecular sieve chromatography, and the loading amount is 10% of the volume of the chromatographic column. Elute with distilled water, collect the eluate to concentrate, apply Sephadex LH-20 column chromatography on the concentrated solution, collect the eluate, and freeze-dry to obtain safflower yellow; determined by high performance liquid chromatography, the content of safflower yellow is 99.6% . See attached figure 2 .
Embodiment 3
[0163] Take safflower medicinal powder, add 10 times of water, heat to 90°C, keep warm for 40 minutes, filter and cool the filtrate. Add 8 times of water to the filter residue, heat to 90°C, keep warm for 20 minutes, filter, and cool. Then add 8 times of water to the filter residue, heat to 90°C, keep warm for 20 minutes, filter, cool, and combine the filtrate to stand for 2 hours. After the supernatant is centrifuged, use an ultrafiltration membrane to remove macromolecular impurities. Macroporous Adsorption Resin D 4020 Adsorption, elution with deionized water, collection of the eluate, concentration through the membrane, the concentrated solution was subjected to molecular sieve chromatography, and the loading amount was 12% of the volume of the chromatographic column. Elute with distilled water, collect the eluate, and freeze-dry to obtain safflower yellow; determined by high-performance liquid chromatography, the content of safflower yellow is 86.1%.
