Abstract
Grapevine (Vitis vinifera L.) is one of the main plants of economic importance in the world. The development and adaptation of this plant, which is of great importance economically, to have the desired characteristics, is of great importance. The plant is an extremely important resource not only in terms of its fruit, but also because of the presence of secondary metabolites contained in its cellular structure. One of these secondary metabolites is resveratrol. Resveratrol is a metabolite synthesized in high amounts in grapevine, leaf and grape bark. The aim of the study was to determine the amount and content associated with phenolic content of 99 grapevine varieties protected in the Aegean region in Turkey. Our specific goal with this study was to determine an important parameter for Plant Breeding with data obtained as a result of using ultra-high performance liquid chromatography (HPLC) for the first time in grapevine varieties of the Aegean region. As a result of the analysis, the amount of resveratrol varies between 0-90 mg/kg. At the same time, the total phenol amount analysis was performed to determine the phenolic amount between grapevine types. Compared to plants capable of producing resveratrol, processed or fresh products of the vine are known to be widely consumed by a very large audience. For this reason, it reveals the importance of breeding studies to increase the content of resveratrol.
