Resveratrol is a phytoalexin found in several plant tissuesand present in wines, which is supplied as a nutritionalsupplement. Different studies have revealed its beneficialeffects as anticancer, antiviral, neuroprotective, antiaging,and anti-inflammatory natural active principle. The assayingof resveratrol by mass spectrometry and isotopedilution method, using a stable [2H4] analogue, hasrequired a full elucidation of its gas-phase H/D isotopomerization.Either selected ion monitoring (SIM) ormultiple reaction monitoring (MRM) methods havebeen used for the evaluation of the amount of resveratrolpresent in wine and plasma samples in the negativeionization mode. In all instances the acquired accuracy,limit of quantitation (LOQ), and limit of detection(LOD) are fit for the intended purpose of the assay.

Abstract
Resveratrol is a phytoalexin found in several plant tissuesand present in wines, which is supplied as a nutritionalsupplement. Different studies have revealed its beneficialeffects as anticancer, antiviral, neuroprotective, antiaging,and anti-inflammatory natural active principle.
