Resveratrol, as a non-flavonoid polyphenolic compound, is not only a phytoalexin in plants��but also has antioxidant, anti-tumor, lipid-regulating activity. Recent in vivo and vitro studies have demonstrated that resveratrol can inhibit and even reverse melanoma initiation, promotion and progression. The anti-tumor effects of resveratrol may be mediated by resisting oxadation, blocking cell cycles, promoting apoptosis and inducing differentiation of tumor cells��interfering related signal transduction and inhibiting angiogenesis��
