Özet
Sixteen red grape cultivars (Md. Jean Matthias, Okuzgozu, Muscat Hamburg, Cabarnet Sauvignon, Tekirdag Cekirdeksizi, Gewurztraminer, 2B/56, Kalecik karasi. Carignan, Kokulu Siyah, Alfonse Lavallee, Bogazkere, Adakarasi, Papazkarasi, Mourvedre and Cinsaut) which are grown in Tekirdag Viticulture Research Institute were analyzed for determination of antioxidant activities, total phenolics, anthocyanins, external colour, polyphenoloxidase activities, sugar and acidity. The lowest antioxidant activity (percentage of inhibition on peroxidation in linoleic acid system; AA) was determined in Tekirdag cekirdeksiz extracts as 87.58% and the highest AA was in Mourvedre (93.78%). Total phenolic content (TP) varied from 817 to 3062 mu g/ml GAE in the same varieties, respectively. The total anthocyanin (TA) content ranged from 40.3 to 990.8 mg/l fresh weight. The lowest PPO activity was found in Bogazkere and the highest was in Kalecik karasi. The total sugar content in the analyzed varieties varied between 13.29 and 24.46%. There was stronger correlation between AA and TP than AA and TA. (c) 2006 Elsevier B.V. All rights reserved.
