Resumo: 	ABSTRACT Pineapple is widely consumed and appreciated not only due to its taste and aroma, and also to its nutritional, functional and antioxidant properties, including its vitamin C and carotenoid contents. Brazil is one of the largest world’ pineapple producer, and Pérola and Smooth Cayenne cultivars are the most commonly grown and marketed, but their susceptibility to fusariosis can compromise cultivation. New cultivars resistant to this pathogen are available to meet the demands of pineapple producers and consumers. The aim of this study was to evaluate the content of bioactive compounds and antioxidant activity of pineapple fruits of Imperial, Victoria, IAC Fantástico and Gomo de Mel cultivars, as well as traditional Pérola and Smooth Cayenne cultivars. Fruits grown in the Triângulo Mineiro region were evaluated by colorimetry, determination of ascorbic acid and phenolic compounds by spectrometry, antioxidant activity by ABTS and carotenoid profile by HPLC. Regarding color, Gomo de Mel cultivar showed lower brightness and higher value of parameter b*, indicating a more intense yellow color in this fruit. This result is consistent with the highest carotenoid concentration in this cultivar. Another cultivar that stood out was Imperial, which, while maintaining high carotenoid levels, also showed high concentrations of vitamin C and phenolic compounds, and higher antioxidant activity. Victoria cultivar showed low levels of bioactive compounds and antioxidant activity, even lower than IAC Fantástico cultivar, which showed levels of bioactive compounds similar to traditional Pérola and Smooth Cayenne cultivars.
