An integrative review of Açaí (Euterpe oleracea and Euterpe precatoria): Traditional uses, phytochemical composition, market trends, and emerging applications.

The increasing trade and popularity of açaí prompt this review. Therefore, it is imperative to provide an overview of the fruit's characteristics and the available data on its marketing, research, and products derived from its pulp and seeds to comprehend the current state of the açaí industry. Concerning food applications, it was observed that there is still room for developing processes that effectively preserve the bioactive compounds of the fruit while also being economically feasible, which presents an opportunity for future research.

Antioxidant and antidepressant-like activities of semi-synthetic α-phenylseleno citronellal.

In this study, the antioxidant and antidepressant-like activities of the semi-synthetic compound α-phenylseleno citronellal (PhSeCIT) and the natural terpenoid R-citronellal (CIT) were evaluated. The biological potential of PhSeCIT and CIT was evaluated by antioxidant in vitro assays, such as 1,1-diphenyl-2-picryl-hydrazyl (DPPH), 2,2-azinobis(3-ethylbenzothiazoline-6-sulfonate) (ABTS), ferric ion reducing antioxidant power (FRAP) and linoleic acid oxidation. The compounds were also assessed by ex vivo tests to determine the acute toxicity, levels of thiobarbituric acid reactive species (TBARS), δ-aminolevulinate dehydratase (δ-Ala-D) and Na(+)/K(+) ATPase activities.

Antioxidant properties of (R)-Se-aryl thiazolidine-4-carboselenoate.

The antioxidant potential of organoselenium compounds has been extensively investigated because oxidative stress is a hallmark of a variety of human diseases. In this study, we report the influence of substituent groups on the antioxidant activity of (R)-Se-aryl thiazolidine-4-carboselenoate (Se-PTC) in several in vitro assays. The amino group in the thiazolidine ring affects the antioxidant activity of the compound.

Involvement of serotoninergic and adrenergic systems on the antidepressant-like effect of E. uniflora L. leaves essential oil and further analysis of its antioxidant activity.

In this work we evaluated antidepressant-like effect of E. uniflora leaves EO employing the tail suspension test. The involvement of serotonergic and adrenergic systems was appraised.

Essential oil of the leaves of Eugenia uniflora L.: antioxidant and antimicrobial properties.

Essential oil (EO) of the leaves of Eugenia uniflora L. (Brazilian cherry tree) was evaluated for its antioxidant, antibacterial and antifungal properties. The acute toxicity of the EO administered by oral route was also evaluated in mice.
