Introduction: Epidemiological studies have demonstrated that fruit polyphenols can inhibit the oxidation of lipoproteins of low density (LDL), factor that trigger cardiovascular illnesses. Therefore, this work evaluated the antioxidant power of tropical fruits polyphenols, that never have been studied, present in papaya (Carica papaya), soursop (Annona muricata), mammee (Pouteria sapota), guava (Psidium guajava), banana cv. vietnamese (Musa paradisiaca) tamarind (Tamarindus indicus). Methods: The oxidation was performed at 37°C with different concentrations of polyphenols. The oxidation products were measured by the 2-tiobarbituric acid method. The IC50 was estimated as an antioxidant quality index and the Antioxidant Potential per Serving (APS) as a parameter that categorize the fruits relating the quality and quantity of phenols. Results: The Tamarindus indicus and Pouteria sapota evidenced the best antioxidant quality of polyphenols. Likewise, the Tamarindus indicus and Psidium guajava showed the biggest APS.
