Content of Polyphenols in Grape of Different Cabernet Franc Clones Selected in Serbia

Abstract

Polyphenols are a large group of structurally diverse compounds widely represented in plants. To a large extent contribute to the nutritional and organoleptic characteristics of fruits and vegetables. The aim of the study was to determine the contents of a selected flavan-3-ols in grape of Cabernet Franc clones (No. 02, 010 and 012) obtained in the last phase perennial clonal selection of the variety in the Republic of Serbia. The enriched content of catechin, epicatechin, epigallocatechin, gallocatechin gallate and catechin gallate, compared to the standard and the other two clones specifically allocated No. 010.

Polifenoli su velika grupa strukturno različitih jednjenja široko zastupljenih u biljkama. U velikoj meri doprinose hranjivosti i organoleptičkim osobinama voća i povrća. Cilj rada bio je određivanje sadržaja odabranih flavan-3-ola u grožđu Cabernet Franc klonova (No.02, 010 i 012) dobijenih u poslednjoj fazi višegodišnje klonske selekcije sorte u Republici Srbiji. Po obogaćenom sadržaju katehina, epigalokatehina, epikatehina, epikatehin galata, i katehin galata u grožđu u odnosu na standard i druga dva klona posebno se izdvaja klon No. 010.
