Using liposomes as carriers for polyphenolic compounds: the case of trans-resveratrol.

Resveratrol (3,5,4'-trihydroxy-trans-stilbene) is a polyphenol found in various plants, especially in the skin of red grapes. The effect of resveratrol on human health is the topic of numerous studies. In fact this molecule has shown anti-cancer, anti-inflammatory, blood-sugar-lowering ability...
