| titleOfInvention | A method for extracting tea saponin |
| abstract | The invention relates to natural product separation technology and discloses a method for extracting tea saponin. The method comprises the following steps: (1) extracting by contacting the tea dregs raw material with an extraction solvent, collecting the extract and drying it to obtain crude tea saponin; (2) combining the crude tea saponin obtained in step (1) with Water is mixed to obtain a tea saponin solution, and the tea saponin solution is separated by a macroporous adsorption resin column, then eluted with an eluent and collected, and the eluent contains water and an organic solvent; (3 ) after removing the organic solvent in the eluent, mixing with a flocculant for flocculation, separating solid from liquid and collecting the clear liquid, and drying the clear liquid II. The extraction method of the invention can not only improve the purity of the finally prepared tea saponin, but also improve the yield of the tea saponin. |
