The concentrations of 22 components of wine, including most of those that have been shown to possess significant biological properties, have been determined by a fast and simple analytical method based on gas chromatography with mass spectrometric detection in the selective ion monitoring mode (GC/MS-SIM). The procedure involves an easy liquid–liquid extraction and derivatization methods of flavanols, phenols and carboxylic acid, using a very small wine volume. The average recovery (Rcv) ranged from 73 to 107% and linear regression coefficients (r2) were in a range of 0.981 ≤ r2 ≥ 0.999. The GC/MS-SIM technique gives good specificity and sensitivity, and can therefore be suitable for routine monitoring of the concentration of individual phenolic antioxidants during winemaking and the aging process.
