Migraine headache is a prevalent condition that places a substantial burden on the healthcare system. It is known that certain foods, food additives, alcohol, caffeine, stress, sensory stimuli, disruptions in sleep-wake patterns, hormonal changes, and many other things may trigger migraines. Red wine is a frequently reported trigger for migraines and other headaches but it is unclear what substance(s) in red wine triggers headache and why red wine is more associated with headache than white wine, sparkling wines, or spirits.

Resveratrol (3,5,4'-trihydroxystilbene) is one of the most abundant polyphenols in red grapes, and red wine represents one of the most important dietary source of this compound. Although its beneficial properties on human health have been widely investigated over the last 30 years, very little is known about its derivatives. Resveratrol can indeed undergo glycosylation, oligomerization and, upon UV-light exposure, it can isomerize from the trans- to the cis-isomer, which can further cyclize to 2,4,6-trihydroxyphenanthrene (THP).

Resveratrol (3,5,40-trihydroxystilbene) is a natural compound that can be found in high concentrations in red wine and in many typical foods found in human diet. Over the past decades, resveratrol has been widely investigated for its potential beneficial effects on human health. At the same time, numerous analytical methods have been developed for the quantitative determination of resveratrol isomers in oenological and food matrices.
