| titleOfInvention | Method for comprehensively extracting dye lignin and kaempferol from sophora fruit |
| abstract | The invention provides a method for comprehensively extracting dye lignin and kaempferol from sophora fruit. The technical concept is shown in the steps as follows: 1, crushing raw materials, hydrolyzing through acid water, and extracting acidolysis slag through an organic solvent; 2, combining an extracting liquid, and concentrating and filtering the extracting liquid to obtain precipitate which is a mixture of kaempferol and dye lignin; 3, extracting the obtained precipitate through alkaline liquid, and centrifugally separating to obtain the precipitate which is kaempferol and obtain the supernate which is dye lignin; 4, dissolving the obtained precipitate through the organic solvent, and adding an absorbent to be purified, and filtering, concentrating, and centrifugally separating to obtain faint yellow powder which is kaempferol; and 5, discoloring the supernate obtained in step 3 through the absorbent, and filtering, then adjusting the pH (Potential Of Hydrogen), standing and precipitating, and centrifugally separating to obtain the white powder which is the dye lignin. With the adoption of the method provided by the invention, the problem of the prior art that the resource is wasted because two products cannot be comprehensively developed can be overcome, the extracting step is optimized, the producing cost is reduced, and the operability is improved. |
