✦ Synopsis

Abstract

Red wine represents a complicated system of phenolic compounds which give typical properties to individual varieties. Anthocyanin pigments represent a determinant group and therefore special attention is given to its analysis. The separation in an acceptable time, the selective separation with a typical gaussian curve and the reproducibility are still a problem.

Fundamental works regarding the analysis of flavonoids and anthocyanin pigments by HPLC are the isocratic methods using 10% HCOOH in a 50% methanol‐water solution [1, 2]. In further works, different mobile phases at isocratic and gradient elution for the production and control of wine [3 – 5] or for comparison of the recommended methods of analysis [6] have been used.

The levels of trans-resveratrol in 36 commercial red wines produced in the southern region of Brazil have been measured using a direct injection isocratic UV-HPLC method. The concentration of trans-resveratrol ranged from 0.82 to 5.75 mg/L with a mean value of 2.57 mg/L (R.S.D.%"1.99).
