Proximal chemical characterization and antioxidant activity of Persea americana leaves cv Hass, Fuerte y Criollo

Abstract

The aim of this work was to determine the proximal chemical composition of leaves and infusion Persea americana cv Hass, Fuerte and Criollo, as well as, their antioxidant activity by standardized analytical methods. To carry this out, P. americana leaves were analyzed according to moisture content (fresh and dehydrated), only in the sampling area from Criollo variety was found that produced green and purple fruits, therefore, the leaves of these trees were also evaluated, in order to determine if the proximal composition and antioxidant activity depends on these factors. The results indicated that there is a statistically significant difference in the proximal composition between P. americana leaves of the three varieties evaluated, as well as, their antioxidant activity, with dry leaves infusion of the Criollo variety with green fruit showing the highest activity antioxidant (70 % Inhibition ABTS).
