AI Technical Summary
⚠Technical Problem
In the existing technology, the dosage of natural plant extracts in cosmetics is relatively high, resulting in high production costs, and the whitening activity still needs to be improved.
⚗Method used
Using a specific ionic liquid extraction method, a plant extract composition was prepared by mixing Brazillian cocoa fruit and wolfberry polysaccharide in a mass ratio of 1:1-5, using 1-butyl-3-methylimidazole hexafluoride. Phosphate ionic liquid and cyclic ultrasonic extraction technology improve extraction efficiency and activity.
🎯Benefits of technology
The dosage of Brazillian cocoa fruit is reduced, which reduces the production cost. At the same time, it significantly improves the effect of inhibiting tyrosinase activity and enhances the whitening effect.

Abstract
The invention discloses a plant extract composition. The plant extract composition is prepared by mixing a paullinia cupana fruit extract and lycium barbarum polysaccharide according to a mass ratio of 1:(1-5). A preparation method of the paullinia cupana fruit extract comprises the following steps: (1) paullinia cupana fruits are dried and crushed, an ionic liquid ethanol solution is added, aftersealed infiltration is conducted for 1-2 h, a 30-50 V / V% ethanol solution is added, heating is conducted to achieve the reflux temperature, reflux extraction is conducted for 1-2 hours, filtering isconducted, filtrate is collected, and concentrating is conducted to obtain a crude extract; and (2) the crude extract is diluted with a proper amount of water, hydrochloric acid is added to adjust a pH value to 2.0-5.0, extracting with diethyl ether is conducted for 2-3 times, organic phases are combined, concentrating under reduced pressure is conducted, and drying is conducted. Compared with theprior art, a smaller amount of paullinia cupana fruits is adopted, so that the production cost is reduced, and the technical effect of better inhibiting tyrosinase activity is further achieved.
