| titleOfInvention | A kind of method extracting stilbene glucoside from Tuber Fleeceflower Root |
| abstract | The invention discloses a kind of method extracting stilbene glucoside from Tuber Fleeceflower Root, belong to biomedicine technical field.Extracting method of the present invention, comprises the following steps: 1) get after Tuber Fleeceflower Root powder mixes with the alkali of its quality 0.5 ~ 3%, add the water mixing of Tuber Fleeceflower Root opaque amount 8 ~ 10 times, obtain Tuber Fleeceflower Root powder suspension liquid; 2) by concentrated after Tuber Fleeceflower Root powder suspension liquid refluxing extraction, concentrated solution is obtained; 3) in concentrated solution, add its quality 3 ~ 5 times, volume fraction is the organic solvent of 90 ~ 95%, completely rear filtration to be precipitated, collects filtrate; 4) in filtrate, add extraction into ethyl acetate, collect aqueous phase, leave standstill after crystallization is complete, collect crystallization and obtain stilbene glucoside.The inventive method preparation technology is simple, with low cost, and obtained stilbene glucoside purity is greater than 95%, and product is without chemical agent residue, leaching process environmental friendliness, to reagent and equipment requirements low, be applicable to large-scale industrial production. |
