Abstract

Phenolic compounds represent secondary plant metabolites which play an important physiological and morphological role in plant growth and reproduction. They also provide a protection against pathogens and predators. The aim of this study is to obtain an overview of changes in the composition and phenolic compounds content, more precisely flavonols, flavanols, hydroxycimetic and hydroxybenzoic acids present in the leaves of four different grapevine varieties. The extracts were analyzed by high performance liquid chromatography. Based on the obtained results, significant variability in mass shares of phenolic compounds between varieties was determined by individual sampling terms, as well as significant variability in the content of phenolic compounds within the same variety during different sampling terms.

Keywords
