摘      要：Objective:To improve the knowledge on the metabolite profile of five red grapes from D?o region(Portugal),concerning to the phenolic characteristics(coloured and non-coloured phenolics) and organic acid ***:Five red grapes collected from D?o region were *** profiles of phenolic compounds and organic acids were estimated by high-performance liquid chromatography with diode-array detection and high-performance liquid chromatography with UV detector,***:Totally 24 phenolic compounds were identified,and distributed by several classes:8 anthocyanins,1 hydroxybenzoic acid,4 hydroxycinnamic acids,1 stilbene,4flavan-3-ols,6 ***,10 organic acids were detected in all *** contents of each phenolic class and organic acids amounts varied significantly among the different grape cultivars *** principal components analysis differentiates the Touriga Nacional from the other varieties due to their high contents in anthocyanins,non-coloured phenolics and organic *** Nacional is an important red grape cultivar,highly esteemed in D?o region for its ability to produce high quality ***:The results suggest that the red grapes from D?o region present a good composition in bioactive compounds,being important for the production of wines with superior quality.
