Determination of chemical composition, antioxidant activity, mass spectrometry and cytotoxicity of the Aiphanes aculeata palm fruit

Abstract

Berry-type fruits from Arecaceae palms have excellent nutritional, functional and economic characteristics. This study aimed to evaluate the pulp of the Aiphanes aculeata palm fruit through the analysis of proximate composition, physicochemical parameters, micronutrients, total phenolics, antioxidant activity and cytotoxicity. In relation to macronutrients, low levels of lipids, proteins and fibers, and high levels of carbohydrates and sugars were determined. Among the micronutrients analyzed (Ca, Mg, Zn, Fe, P and K), potassium (933.04 mg/100 g) was the most abundant element in the fruit. Regarding the analysis of vitamin C, the value determined was 46.97 mg/100 g. The DPPH, FRAP and ABTS assays were used to evaluate the antioxidant activity. The extracts showed antioxidant activity in the methods used, providing potential for their application in the composition of the food products formulations with functional properties since there was no cytotoxic potential in normal cells (L-929).
