| titleOfInvention | A method of extracting separation casurin from tea dust |
| abstract | The method that the invention discloses a kind of to extract separation casurin from tea dust.This method comprises the steps of: (1) taking tea dust, ethanol solution, ultrasonic extraction is added by the solid-to-liquid ratio of 1g: 10~20mL, membrane filtration obtains crude extract；(2) basic zirconium phosphate is added into crude extract in the ratio that 0.3~0.5g basic zirconium phosphate is added in 1mL crude extract, shaking table oscillation 12~for 24 hours, it is centrifugated out basic zirconium phosphate and is washed with water；(3) by 0.1g: 1mL solid-to-liquid ratio toward phosphoric acid deionized water solution is added in the basic zirconium phosphate after washing, shaking table vibrates 12h, is centrifugally separating to obtain desorption liquid, membrane filtration, filtrate be freeze-dried to get.The method of the present invention is high to the rate of recovery of casurin, product impurity is low, and easy to operate, environmentally protective, low to production equipment requirement, product cost is low, is adapted for large-scale production. |
