چکیده انگلیسی
A survey of resveratrol content in wines of the four Aragón designations of origin (Borja, Cariñena, Calatayud and Somontano) was carried out. Concentrations of trans- and cis-resveratrol isomers of 98 commercial wines of the four designations of origin, from several vintages, were analyzed by means of reverse-phase high-performance liquid chromatography. Concentration of trans-resveratrol ranged from 0.32 to 4.44 mg/l in red wines and from 0.12 to 2.80 mg/l in rosé wines. cis-Resveratrol levels ranged from 0.20 to 5.84 mg/l in red wines and from 0.02 to 3.17 mg/l in rosé wines. The grape variety influenced resveratrol contents in wines from the different regions. The highest trans/cis ratios were found in Somontano (4.50) and Calatayud wines (2.90), both of the Tempranillo variety. However, a discriminant analysis applied to the concentrations did not show significant differences between young red wines nor between rosé wines of the four designations of origin.
