Euterpe oleracea, also known as Acai berry or fruit

Euterpe oleracea is a common, tall, slender palm tree which grows 15 to 25 m in height. Euterpe oleracea tree produces an edible fruit which grows in bunches. The Euterpe oleracea fruit is round, 1-2 cm in diameter, with a single large seed inside surrounded by stringy fibrous sheaths and a thin oily coating.

Euterpe oleracea nutritional value
Euterpe oleracea has a high content of lipids, protein, ash and total dietary fiber. Most of the Euterpe oleracea fat is oleic acid. Euterpe oleracea has polyphenols 2 to 5 g/100 g; tannins; anthocyanins 1 g/100g.

Absorption and Biological Activity of Phytochemical-Rich Extracts from Acai (Euterpe oleracea Mart.) Pulp and Oil in Vitro.
J Agric Food Chem. 2008 April. Pacheco-Palencia LA, Talcott ST, Safe S, Mertens-Talcott S.
This study investigated the absorption and antiproliferative effects of phytochemical extracts from Euterpe oleracea pulp and a polyphenolic-enriched Euterpe oleracea oil obtained from the fruit pulp of the Euterpe oleracea berry. Standardized extracts were characterized by their predominance of hydroxybenzoic acids, monomeric flavan-3-ols, and procyanidin dimers and trimers. Polyphenolic mixtures (0-12 microg of gallic acid equiv/mL) from both Euterpe oleracea pulp and Euterpe oleracea oil extracts inhibited cell proliferation by up to 90%, which was accompanied by an increase of up to 2.1-fold in reactive oxygen species. Absorption experiments using a Caco-2 intestinal cell monolayer demonstrated that phenolic acids such as p-hydroxybenzoic, vanillic, syringic, and ferulic acids, in the presence of DMSO, were readily transported from the apical to the basolateral side along with monomeric flavanols such as catechin and epicatechin. Results from this study provide further evidence for the bioactive properties of Euterpe oleracea polyphenolics and offer new insight on their composition and cellular absorption.
