| In the present study, the effect of ethanol extracts of leaf and root of Rosa multiflora on the proliferation of B16 cells, tyrosinase activity and melanin synthesis were investigated. 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide(MTT) assay demonstrated that the cell viability upon treatment with Rosa multiflora extract(0-200 ${mu}g$/ml) was similar to that of untreated control. Treatment with leaf or root extracts(200 ${mu}g$/ml) decreased the in vitro tyrosinase activity to about 65% of that in untreated control. Similarly, the intracellular tyrosinase activity of B16 cells decreased in a concentration-dependent manner. Furthermore, the melanin synthesis of B16 cells decreased by the two extracts in a concentration dependent manner. However, the extracts did not change the level of tyrosinase mRNA, as determined by RT-PCR. These results demonstrated that the Rosa multiflora extracts inhibit the tyrosinase dependent melanin biosynthesis, and therefore, are candidates for skin-whitening agents. |
