Antioxidant activity of selected nutritional values of plums typical of the White Carpathian Mountains

Abstract

Práce popisuje krajové odrůdy švestek a slív v oblasti Bílých Karpat. Byla zjištěna vysoká hodnoty polyfenolů (348 ? 495 mg GAE.100 g-1 FW). Vysoký byl i korelační koeficient mezi antioxidační kapacitou a množstvím fenolických látek (r2 = 0,893). Článek je příspěvkem k popularizaci evropských odrůd švestek a jejich využití pro potravinářskou a šlechtitelskou praxi.

The paper presents a description of chemical characteristics of selected varieties of plum and prune trees (Prunus domestica L.). Traditional commercial cultivars were compared with typical regional varieties originating from the same locality of the White Carpathian Mountains. In this region, growing, use of specific local varieties and processing of fruit for alimentary purposes is a traditional activity which has been performed there for centuries. Regional varieties showed outstanding nutritional properties, especially as far as the total content of phenolic substances was concerned (348 ? 495 mg GAE.100 g-1 FW) ; this parameter was highly correlated with the total antioxidant capacity of this fruit (r2 = 0,893). A higher content of minerals and pectin in some local varieties was also of interest. This paper demonstrates beneficial properties of some less known but regionally typical European varieties of prunes and plums and contribute to their wider use in breeding practice and also as a potential source of nutrients for human diet.
