Chemical composition and antioxidant properties of native Ecuadorian fruits: Kunth Kunth, and .

The native berries of South America present promising marketing opportunities owing to their high antioxidant content, notably rich in anthocyanin and phenolic compounds. However, Ecuador's endemic fruits, primarily found in the wild, lack comprehensive data regarding their phytochemical composition and antioxidant capacity, underscoring the need for research in this area. Accordingly, this study evaluated the total phenolic, anthocyanin, flavonoid, resveratrol, ascorbic acid, citric acid, sugars, and antioxidant content of three native Ecuadorian fruits: mora de monte ( Kunth), mortiño ( Kunth), and tuna de monte ().

Antioxidant Capacity through Electrochemical Methods and Chemical Composition of and from the Ecuadorian Amazon.

This study evaluated the antioxidant properties and chemical composition of the seeds, pulp and peels of Ungurahua () and Pasu ()-fruits, native to the Ecuadorian Amazon. The antioxidant capacity was measured by 1,1-diphenyl-2-picrylhydrazyl (DPPH) and cyclic voltammetry (antioxidant index 50 (AI)) assays; differential pulse voltammetry was used to evaluate antioxidant power using the electrochemical index. The total phenolic content, as well as the yellow flavonoid and anthocyanin content, were quantified via spectrophotometry.
