Sažetak
In this study, bioactive polyphenolic compounds from red wines were investigated. For the characterization of individual polyphenolic compounds belonging to phenolic acid and flavanol class, easy and reliable high performance liquid chromatography method with photodiode array detection was developed. Total polyphenols and total flavonoids were also investigated by using simple spectroscopic methods. All methods were checked for their linearity, limit of detection, limit of quantification and precision. Developed and validated procedures were applied for the determination of polyphenolic compounds in two wines from Baranja vineyards, Croatia. The most abundant compounds found in red wines were (-)-epicatechin and gallic acid followed by p-coumaric acid, (+)-catechin. The developed method were shown to be precise for the determination of polyphenolic compounds from red wines.
