| titleOfInvention | A kind of plant extract composition and its application in whitening cosmetics |
| abstract | The invention discloses a plant extract composition, which is prepared by mixing Brazilian cocoa fruit extract and Lycium barbarum polysaccharide in a mass ratio of 1:1-5. The preparation method of the Brazilian cocoa fruit extract is as follows: (1) Dry and pulverize Brazilian cocoa fruit, add ionic liquid ethanol solution, seal and soak for 1-2 hours, add 30-50V/V% ethanol solution, heat to reflux temperature, extract under reflux for 1-2 hours, filter, collect The filtrate was concentrated to obtain a crude extract; (2) after the crude extract was diluted with an appropriate amount of water, the pH was adjusted to 2.0-5.0 by adding hydrochloric acid, extracted with ether for 2-3 times, the organic phases were combined, concentrated under reduced pressure and dried. Compared with the prior art, the present invention adopts a smaller amount of Brazilian cocoa fruit, which not only reduces the production cost, but also achieves a better technical effect of inhibiting the activity of tyrosinase. |
