Ten grape-vine cultivars (5 white and 5 red skinned) were cultivated in south-east region of Poland. Samples were frozen and for analyzes extracts in 80 % MeOH were prepared. Contains of total phenols, phenylpropanoids, flavonols and anthocyanins were measured, using UV/VIS method. Additionally, radical scavenging activity with DPPH was determind. In red skinned fruits content of phenolic compounds was higher than in white skinned ones. Cultivars showed great diversity: the highest level of phenolics was observed in ‘Heridan’ and the lowest in ‘Bianca’ cultivars. Radical scavenging activity (RSA) was also very high in red grapes, especially in skin (over 90 % of free radical was neutralized). Antioxidant activity of white fruit cultivars wa...
