2,4,6-trihydroxyphenanthrene: a new trans-resveratrol derivative detected in red wine after UV irradiation.

T2,4,6-trihydroxyphenanthrene (THP) results from cyclization of the trans-to the cis-isomer of resveratrol one of the most abundant polyphenols in red grapes and red wine. It has been demonstrated that THP can induce DNA damage through a pro-oxidant mechanism. On the other hand, due to the extended delocalization and conjugation of the πelectrons over the entire molecule, THP displays a significantly increased antioxidant activity compared to RSV with potential benefits on human health. Whatever the effect of THP on human health, it becomes important to establish its actual presence not only in RSV-containing food and beverages but even in cosmetics that, by their nature, are subject to UV radiation.

Consumption of wine is a controversial issue, therefore, discussions forums like the conference that will be held in Vila Nova de Gaia at June 4 are very important.
