Mango varieties "espada", "rosa" and tommy atkins: bioactive compounds and antioxidant potential

The aim of this work was to determine the amount of ascorbic acid, total phenolics and carotenoids and evaluate the antioxidant potential of mango varieties "Espada", "Rosa" and Tommy Atkins. The fruits were ground to obtain the fresh pulp and waste resulting was dried, crushed to pass through sieve. Hydroacetone, hydromethanolic and aqueous extracts, obtained through sequential extraction procedure from pulp and dehydrated waste were screened for their antioxidant activity by DPPH free radical scavenging. The "espada" and Tommy Atkins mango showed similar levels of total carotenoids, however less than Rosa mango. The Tommy Atkins mango exhibited the lowest content of ascorbic acid and the espada mango the highest level of phenolic compounds. The extract hydroacetone (pulp and dehydrated waste) exhibited a strong free radical scavenging capacity (>80%).
