Abstract
Objectives : In this study, we investigated the effect of ethanol extract from Rosa rugosa Thunb. flowers(ERF) on the activities of antioxidant, antiwrinkle and whitening.

Methods : We measured antioxidant efficacy of ERF by using 1,1-diphenyl-2- picrylhydrazyl(DPPH) assay. Also we confirmed the inhibitory effect of ERF on collagenase activity and melanin synthesis by using collagenase assay kit and dihydroxiphenylalanine staining, respectively. To evaluate the anti-inflammatory effects of ERF, we examined the inflammatory mediator IL-6.

Results : ERF showed highly efficacy in DPPH radical scavenging activity. ERF dose-dependently suppressed collagenase activity. Ultraviolet-induced production of IL-6 decreased by ERF treatment. In B16F10 cell, ERF significantly reduced tyrosinase activity and melanin synthesis.

Conclusions : From the above results, it was indicated that ERF could be utilized as anti-aging and whitening cosmetic ingredients
