| titleOfInvention | A kind of Sophora japonica extraction process |
| abstract | The invention discloses a process for extracting Sophora japonica. The crude Sophora japonica pigment is finally extracted through a series of steps, such as fresh Sophora japonica, immersion in selected water, concentration and crystallization, centrifugation, ethanol soaking and sedimentation, suction filtration, and microfiltration and spray drying. The extracted crude locust flower pigment is refined and purified. The present invention 1, utilizes the property of rutin structure that contains multiple phenolic hydroxyl groups, is phenolic acid, and can be dissolved in alkaline water, can be extracted with an alkaline solvent, and the extract can be precipitated after adding acid; It has low solubility and high solubility in hot water for extraction to improve preparation efficiency; at the same time, the rutin structure has low solubility in cold ethanol, high solubility in hot ethanol, and high solubility in hot water and low solubility in cold water. After the rutin is dissolved by heating with a solvent, it is filtered while hot, and the filtrate can be precipitated after being cooled to achieve the purpose of separation. |
