Dendrobium moniliforme (DM) is a valuable and versatile herbal medicine with the anecdotal claims of antioxidant and anti-inflammation. In the present study, we investigated the whitening and anti-wrinkling effects of DM under various conditions with B16F10 melanoma cells and human dermal fibroblasts. The DM extract inhibited melanin contents and tyrosinase activity in a dose-dependent manner, compared with untreated group. Treatment of the DM extract effectively suppressed the α-MSH-stimulated melanin formation, tyrosinase activity and dendrite outgrowth. Moreover, the α-MSH-induced mRNA expressions of tyrosinase-related protein-1 (TRP-1) and tyrosinase-related protein-2 (TRP-2) and protein expression of tyrosinase were significantly attenuated by DM treatment. We also investigated the DM increased the production of type I procollagen and inhibited TNF-α-induced mRNA expressions of MMP-1, -3 in the human dermal fibroblast. These results indicate that DM may be a great cosmeceutical ingredient for its whitening and anti-wrinkle effects.
