Being a valuable source of important nutrients (starch, fibres, amino-acids, vitamins, minerals) potato tubers represent a complex matrix in the human diet, having potential health benefits. This vegetable has a significant contribution to the dietary intake of some antioxidants such vitamin C, carotenoids and phenolic compounds. The present study evaluated the total content of phenolic compounds (TPC) and of carotenoids (TCC) in skin and flesh of ten Romanian potato genotypes grown in Brasov, over two years. Significant differences of all parameters tested were observed across genotypes. Lower levels of TPC and TCC were found in the flesh than in the skin of the tubers. Blue genotype 'Blue Purple of Galanesti’ had the highest values for all parameters excepting the carotenoids in flesh and skin which were higher in the variety 'Sevastia’. This study contents information regarding the content of valuable micronutrients of several Romanian potato cultivars with good nutritional quality.
