Abstract

The aim of this study was to perform a phytochemical analysis of 28 red wines available on Romanian and also on the international market. The identification of 14 polyphenols and their quantitative analysis were performed by HPLC/ESI-MS (high-performance liquid chromatography-electrospray ionisation tandem mass spectrometry). Resveratrol contents were determined by HPLC/APCI-MS (HPLC coupled online with atmospheric pressure chemical ionization). Total polyphenols and monomeric anthocyanins were assayed by Folin-Ciocâlteu and pH differential methods. The GC-FID (gas chromatography coupled with flame ionization detector) system was used for the volatile congeners determination. The content of 35 toxic metals was investigated using a Q-ICP-MS (Quadruple inductively-coupled-plasma mass spectrometer) analyses. Quality and quantity of polyphenols, volatile congeners and metal content varied greatly among cultivars, and from this point of view, several Romanian wine samples could be considered of high quality when compared with international brands.
