RT Journal Article T1 Trans-Stilbenes in Commercial Grape Juices: Quantification Using HPLC Approaches A1 López Hernández, María Julia Celia A1 Rodríguez Bernaldo de Quirós, Ana Isabel K1 Trans-stilbenes K1 Commercial fruit juices K1 High-performance liquid chromatography K1 Variable wavelength detector K1 Fluorescence detector AB Trans-stilbenes belong to the group of polyphenolic phytoalexins, and occur in many plant foods. These compounds have received great attention by researchers due to their well-known beneficial health effects. In the present study a chromatographic method that comprises the use of variable wavelength (VWD) and fluorescence (FLD) detectors in series for the analysis of trans-stilbenes is presented. The relation of peak-area obtained with both detectors is proposed as an alternative and complementary approach for the rapid identification of these phenolic compounds. The proposed method was applied to determine trans-stilbenes in commercial fruit juices. Trans-piceid was the most common trans-stilbene found in the samples analyzed. The method was validated in terms of linearity, sensitivity and repeatability. Appropriate sensitivity and good linearity (r2 > 0.9991) were achieved.
