The occurrence and content of some polyphenols and the antioxidant activity of compounds present in grape berries, stems and leaves of Vitis vinifera L. were evaluated. Three white and three blue varieties of grapevine were investigated. The contents were determined of trans-resveratrol, trans-piceid, caftaric acid, tryptophan, catechin, epicatechin, total polyphenols, and flavanols, both in healthy material and in the samples of the plant material infested with microorganisms.

Byla hodnocena přítomnost a obsah některých polyfenolů a antioxidační aktivita sloučenin přítomných v hroznech, třapinách a listech révy Vitis vinifera. Byly studovány tři bílé a tři modré odrůdy révy. Byl určován obsah trans-resveratrolu, trans-piceidu, kyseliny kaftarové, tryptofanu, katechinu,epikatechinu, celkových polyfenolů a flavanolů, a to jak ve zdravém rostlinném materiálu, tak infikovaném mikroorganismy.
