Embodiment 1
[0104] (1) Grind 20kg of dried Cordica japonica, add 10 times the amount of 70% ethanol, reflux extraction in a water bath at 65°C for 3 times, each time for 75min, combine the extracts, recover the ethanol, and obtain the extract Ⅰ;
[0105] (2) Dissolve the extract I in water, centrifuge, collect the supernatant to obtain the supernatant II; the supernatant II is purified by column chromatography with AB-8 macroporous adsorption resin, and the diameter-to-height ratio of the resin column is 1 : 8, sample loading volume 7BV, flow velocity is 3BV / h, respectively with deionized water, 10% ethanol solution, 20% ethanol solution eluting macroporous resin, eluent abandons, with 30% ethanol as eluent 7BV Elution and collection of eluate to obtain eluate III; concentrating eluate III and drying to obtain 5.4 g of Saffron Japonica extract.
Embodiment 2
[0107] (1) Grind 20kg of dried Cordica japonica, add 5 times the amount of 80% ethanol, and reflux extract in a water bath at 60°C for 4 times, each time for 70 minutes, combine the extracts, recover the ethanol, and obtain the extract Ⅰ;
[0108] (2) Dissolve the extract I in water, centrifuge, collect the supernatant to obtain the supernatant II; the supernatant II is purified by column chromatography with AB-8 macroporous adsorption resin, and the diameter-to-height ratio of the resin column is 1 : 9, sample loading volume 6BV, flow velocity is 4BV / h, with deionized water, 10% ethanol solution, 20% ethanol solution eluting macroporous resin respectively, eluent abandons, with 30% ethanol as eluent 5BV Elution and collection of the eluate to obtain eluate III; concentrating the eluate III and drying to obtain 5.2 g of Saffron Japonica extract.
Embodiment 3
[0110] (1) Grind 20kg of dried Cordica japonica, add 15 times the amount of 60% ethanol, reflux extraction in a water bath at 70°C for 2 times, each time for 80 minutes, combine the extracts, recover ethanol, and obtain the extract Ⅰ;
[0111] (2) Dissolve the extract I in water, centrifuge, collect the supernatant to obtain the supernatant II; the supernatant II is purified by column chromatography with AB-8 macroporous adsorption resin, and the diameter-to-height ratio of the resin column is 1 : 7, sample loading volume 8BV, flow velocity is 2BV / h, respectively with deionized water, 10% ethanol solution, 20% ethanol solution eluting macroporous resin, eluent abandons, with 30% ethanol as eluent 8BV Elution was carried out, and the eluate was collected to obtain eluate III; the eluate III was concentrated and dried to obtain 5.5 g of Saffron Japonica extract.
