Antioxidant Properties of Amazonian Fruits: A Mini Review of In Vivo and In Vitro Studies

Abstract EN

Brazil, Colombia, Ecuador, Peru, Bolivia, Venezuela, Suriname, Guyana, and French Guiana share an area of 7,295,710 km2 of the Amazon region.

It is estimated that the Amazonian forest offers the greatest flora and fauna biodiversity on the planet and on its surface could cohabit 50% of the total existing living species; according to some botanists, it would contain about 16-20% of the species that exist today.

This region has native fruit trees in which functional properties are reported as antioxidant and antiproliferative characteristics.

Amazon plants offer a great therapeutic potential attributed to the content of bioactive phytochemicals.

The aim of this mini review is to examine the state of the art of the main bioactive components of the most studied Amazonian plants.

Among the main functional compounds reported were phenolic compounds, unsaturated fatty acids, carotenoids, phytosterols, and tocopherols, with flavonoids and carotenoids being the groups of greatest interest.

The main beneficial effect reported has been the antioxidant effect, evaluated in most of the fruits investigated; other reported functional properties were antimicrobial, antimutagenic, antigenotoxic, analgesic, immunomodulatory, anticancer, bronchodilator, antiproliferative, and anti-inflammatory, including hypercholesterolemic effects, leishmanicidal activity, induction of apoptosis, protective action against diabetes, gastroprotective activity, and antidepressant effects.
