This study was performed to improve antioxidant activities and skin-whitening effects of Rubus coreanus Miquel extracts by nano-encapsulation. R. coreanus was extracted at 60℃ and encapsulated by lecithin and gelagine. Nano-encapsulated extracts showed highest free radical scavengering effect as 97.62% in adding sample (500 μg/ml), compared to the extracts from conventional processes. It was showed strong inhibition effect on melanin production test by Clone M-3 cells as 55.23%. High inhibitory potency on tyrosinase was also measured as 155.8% by adding nano-sample of 1 mg/ml. The improvement of biological activity was demonstrated by real time confocal microscope. We could consider that the water soluble extracts of R. coreanus could be definitely enhanced by nano-encapsulated as a potent natural resources for antioxidant and skin-whitening agent.
