Los resultados muestran similitud en la composición de los extractos de las tres zonas estudiadas, y los extractos etanólicos de los frutos de Manzanillo poseen la mayor diversidad de metabolitos secundarios; siendo los más abundantes alcaloides, fenoles, cumarinas y carbohidratos reductores. La actividad antioxidante in vitro fue estimada mediante la capacidad antioxidante total y el poder reductor férrico y el mayor valor de los extractos etanólicos puede asociarse al mayor contenido de fenoles totales determinado por el método de Folin Ciocalteu.

<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT The qualitative phytochemical composition and in vitro antioxidant activity of ethanolic and aqueous extracts of Coccoloba uvifera L. fruits collected in the municipalities of Manzanillo, Niquero and Pilón were evaluated. The results show similarity in the composition of the extracts from the three areas studied and the ethanolic extracts of Manzanillo fruits have the greatest diversity of secondary metabolites; being the most abundant alkaloids, phenols, coumarins and reducing carbohydrates. The in vitro antioxidant activity was estimated by the Total Antioxidant Capacity and the Iron Reducing Power and the higher value of the ethanolic extracts can be associated with the higher content of total phenols determined by the Folin Ciocalteu method. The results make the fruit a potential source of antioxidants and constitute the first report on the composition and antioxidant activity of polar extracts from the fruit of C. uvifera in Cuba.]]></p></abstract>
