Searching trans-resveratrol in fruits and vegetables: a preliminary screening

Resveratrol is a phytoalexin with potent anti-inflammatory, anti-oxidant and anti-carcinogenic effects. The object of this work was to determine whether this promising compound was present in the typical fruits and vegetables used in the Mediterranean diet. Our results indicated the presence of trans-resveratrol in concentrations ranging from 0.2 A mu g/g in tomatoes and 3 lg/g. in strawberries.
