To specify the genotypic variation of Mediterranean Citrus juices, the contents of carotenoids,flavonoids, and vitamin C were determined by high-performance liquid chromatography. A selectionof orange varieties and Mandarin species from the Mediterranean area (Citrus sinensis, Citrus deliciosaTen, and Citrus clementina Hort. ex Tan) was evaluated using carotenoid profiles and flavanonescontents. Among the eight varieties of orange (Salustiana, Hamlin, Shamouti, Pera, Valencia, Maltaise,Sanguinelli, and Cara-cara) and two Mandarin species, only three cultivars (Pera, Sanguinelli, andShamouti) and the two Mandarin species displayed a high content of vitamin A (374, 381, and 272ER L-1 for the three orange cultivars and 1156 and 960 retinol equivalent (RE) L-1 for the Mandarins)due to a high content of 
-cryptoxanthin. These same Citrus were also rich in hesperidin (502, 537,552, 767, and 754 mg L-1, respectively). Principal component analysis allowed the Mediterraneanorange varieties and Mandarin species to be differentiated on the basis of nutritional criteria. Strongcorrelations were observed between -cryptoxanthin and hesperidin (r = 0.92) and between-cryptoxanthin and -carotene (r = 0.98). In contrast, vitamin C content was not correlated withcarotenoids and flavanone glycosides. The Mandarin and orange group was quite distinct. The orangevarieties could be divided in two groups. In addition, a diversity tree allowed a genetic approach todifferentiating Citrus cultivars on the basis of Euclidian distances. This representation showed thatthe hybrid Clementine was nearer to its parent Mandarin than to its parent orange, suggesting that-cryptoxanthin was a dominant genetic factor. With regard to vitamin A, Mandarin and its hybridClementine appeared to be the best Citrus species.Keywords: Citrus sinensis; Citrus reticulata; Mediterranean Citrus; micronutrients; carotenoid;hesperidin; vitamin C; -cryptoxanthin; orange juice, varietal selection
