Abstract
Chemical composition as well as phytochemicals and antioxidant activity of underutilized plants, such as carnauba palm (Copernicia prunifera), provide an informed decision on how to maximize their benefits. This study aimed to evaluate the chemical composition and antioxidant activity of the fruit of carnauba. The total phenolic content (gallic acid equivalents, GAE) of the ethanol extract of the whole fruit, pulp and kernel were 44.6000, 0.0447 and 0.6930 mg GAE/g extract, respectively. The respective total tannin content was 1590.932, 2977.724 and 147.650 ppm in the whole fruit, pulp and kernel. The fruit of carnauba showed 9.84 mg anthocyanins/50 g of fresh pulp. Ethanol extract of whole fruit had a potent antioxidant activity. Thus, the fruit of carnauba has add-value in food industry. Key words: Secondary compounds, carnauba ethanol extract.

The aim of this study was to determine the chemical composition, phytochemical profile and antioxidant activity of the extracts obtained from the fruit of the carnauba palm and its separate parts, namely: the pulp and kernel
Braga (1960) reported that values of protein relatively close to those obtained in the present study for the pulp content (5.46%) and higher values for the kernel (6.89%), compared to those found in present study (6.30, 5.21 and 4.50% in the dried whole fruit, the pulp and fresh kernel, respectively)
Summary
Carnauba palm or Brazilian tree of life [Copernicia prunifera (Miller) H. E. Moore, Arecaceae family] is a palm tree found in the northeastern Brazil and Cerrado biomes, located in some Brazilian regions (D’alva, 2004). The extractive exploitation of the resources offered by. This palm was first described around 1648 by Maregravius and Piso, and subsequently ratified by R. In 1768, upon reporting the first experiments on carnauba wax for candles. Carnauba wax is extracted from the leaves, and used extensively in various
