Embodiment 1
[0032] Sophora japonica was crushed to 30 mesh, 10 kg (sophoricroside content 9.5%) was taken, 20 L of water was added, the pH was adjusted to 5, 200 g of cellulase was added, heated to 50° C., and incubated for 10 hours. Add 60L of 90% ethanol, reflux and extract for 2 hours, extract twice, combine the extracts and concentrate under reduced pressure to 70% alcohol concentration, leave to crystallize for 8 hours, filter the crystals, add 5 times their weight in hot water at 80°C, stir and wash, filter to obtain the dye Crude lignin. The crude genistein was saturated and dissolved with 95% ethanol under reflux, adjusted the pH to 4, left to crystallize for 12 hours, filtered to obtain crystals, added 50% ethanol twice the weight of the crystals, stirred and washed, filtered, and dried to obtain 360 grams of finished product with a content of 99 %.
Embodiment 2
[0034] Sophora japonica was crushed to 60 mesh, 10 kg (sophoricroside content 9%) was taken, 10 L of water was added, the pH was adjusted to 5.5, 100 g of β-glucosidase was added, heated to 45° C., and incubated for 12 hours. Add 80L of 90% ethanol, reflux and extract for 1 hour, extract twice, combine the extracts and concentrate under reduced pressure to an alcohol concentration of 65%, leave to crystallize for 12 hours, filter the crystals, add 6 times their weight in hot water at 70°C, stir and wash, and filter to obtain the dye Crude lignin. The crude genistein was saturated and dissolved with 93% ethanol under reflux, adjusted the pH to 4.5, left to crystallize for 14 hours, filtered to obtain crystals, added 70% ethanol twice the weight of the crystals, stirred and washed, filtered, and dried to obtain 330 grams of finished product with a content of 98 %.
Embodiment 3
[0036] Sophora japonica was crushed to 40 mesh, 10kg (sophoricroside content 9%) was taken, 10L of water was added, the pH was adjusted to 4.5, 200g of amylase was added, heated to 55°C, and kept for 15 hours. Add 60L of 95% ethanol, reflux and extract for 1 hour, extract three times, combine the extracts and concentrate under reduced pressure to an alcohol concentration of 60%, leave to crystallize for 10 hours, filter the crystals and add 6 times its weight in hot water at 80°C, stir and wash, and filter to obtain genistein Vegetarian crude products. The crude genistein was saturated and dissolved with 90% ethanol under reflux, adjusted to pH 5, left to crystallize for 14 hours, filtered to obtain crystals, added 70% ethanol twice the weight of the crystals, stirred and washed, filtered, and dried to obtain 340 grams of finished product with a content of 98 %.
