AI Article Synopsis
- The study examines the chemical composition and biological activities of essential oil from Eugenia hiemalis leaves collected throughout the year.
- A total of 42 compounds were identified, with sesquiterpenes being the most abundant, especially in summer, while monoterpenes were absent.
- The essential oil showed effectiveness against certain Mycoplasma strains but did not exhibit anticholinesterase activity.
Article Abstract
The purpose of this work was to study the chemical composition and antimycoplasmic and anticholinesterase activities of the essential oil of Eugenia hiemalis leaves collected throughout the year. A total of 42 compounds were identified by CG, and are present in almost every seasons. Sesquiterpenes were dominant (86.01-91.48%), and non-functionalised sesquiterpenes comprised the major fraction, which increased in the summer; monoterpenes were not identified. The major components were spathulenol (5.36-16.06%), δ-cadinene (7.50-15.93%), bicyclogermacrene (5.70-14.24%) and β-caryophyllene (4.80-9.43%). The highest oil yield was obtained in summer and autumn. Essential oils presented activity against three evaluated Mycoplasma strains, but no activity was observed in the anticholinesterase assay.

This study evaluates the antioxidant, anti-inflammatory and anticancer activities of camphor, menthol and their equimolar combination. In silico toxicity analysis confirmed the absence of toxic effects for both compounds. Antioxidant activity, assessed by 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays, revealed a synergistic effect of the equimolar combination with IC50 values of 10.

Chicken thigh is a popular and widely consumed meat product. However, its high moisture content and susceptibility to microbial spoilage limit its shelf life. To address this issue, we investigated the efficacy of an edible coating based on alginate nanoparticles (AlgNPs) containing menthol, essential oil (EO), or their combination for extending the shelf life of chicken thigh.

A study was conducted to assess growth performance, methane (CH) emissions, and feeding behavior of feedlot steers consuming backgrounding and finishing diets with an essential oil blend (EO), monensin (Mon), and their combination (EO + Mon). The study was structured as a 2 × 2 factorial, with two feed additive treatments (Control, EO) and two monensin treatments (no Monensin, Monensin). One hundred Angus × steers were evenly distributed across each treatment into four pens, and each dietary phase consisted of four, 28-d periods.
