In this study, we investigated antioxidant activities and whitening effects of Acer mono sap by encapsulation of nanoparticles. Acer mono sap was through ultra high pressure process and then encapsulated by lecithin. Nano-encapsulated The nanoparticles of Acer mono sap showed highest free radical scavengering effect as 89.7% in adding sample (1.0 mg/ml), compared to sap of non-encapsulation. It was showed strong inhibition effect on melanin production test by Clone M-3 cells as 47.8%. High inhibitory of tyrosinase was also measured as 85.8% by adding lecithin nano-particle of 1.0 mg/ml. The nano-particles also showed 14.8% of low cytotoxicity against human normal fibroblast cells in adding 1.0 mg/ml of the highest concentration. These results indicate that Acer mono sap may be a source of cosmetic agents capable of improving whitening effect and antioxidant activites.
