“…A single chemical profile (Mpil-1) was identified in the literature for Myrciaria pilosa . Sobral and Couto, characterized by guaiol (13.7%), E -caryophyllene (11.3%), and β-eudesmol (9.2%), whose essential oil was obtained by hydrodistillation from leaves of a specimen collected in Pernambuco, Brazil [ 37 ]. It was impossible to verify the major constituents’ chemical variability since the species is still poorly studied.…”

“…The oil of M. pilosa , characterized by guaiol (13.7%), E -caryophyllene (11.3%), β-eudesmol (9.2%), and γ-eudesmol (6.6%), presented bactericidal properties against Staphylococcus aureus (MIC, 5 μg/mL) by the broth microdilution method, and antivirulence with reductions of 92.0% and 47.2%, respectively, in the hemolytic action and production of staphyloxanthin [ 37 ].…”

Myrciaria (Myrtaceae) species have been well investigated due to their chemical and biological relevance. The present work aimed to carry out the chemotaxonomic study of essential oils of the species M. dubia, M. floribunda, and M. tenella, sampled in the Brazilian Amazon and compare them with the volatile compositions from other Myrciaria species reported to Brazil and Colombia. The leaves of six Myrciaria specimens were collected (PA, Brazil) during the dry season, and their chemical compositions were analyzed by gas chromatography-mass spectrometer (GC-MS) and gas chromatography-flame ionization detector (GC-FID). The main compounds identified in the essential oils were monoterpenes with pinane and menthane skeletons, followed by sesquiterpenes with caryophyllane and cadinane skeletons. Among the sampled Myrciaria specimens, five chemical profiles were reported for the first time: profile I (M. dubia, α-pinene, 54.0–67.2%); profile II (M. floribunda, terpinolene 23.1%, α-phellandrene 17.7%, and γ-terpinene 8.7%); profile III (M. floribunda, γ-cadinene 17.5%, and an unidentified oxygenated sesquiterpene 15.0%); profile IV (M. tenella, E-caryophyllene 43.2%, and α-humulene 5.3%); and profile V (M. tenella, E-caryophyllene 19.1%, and caryophyllene oxide 41.1%). The Myrciaria chemical profiles showed significant variability in extraction methods, collection sites, plant parts, and genetic aspects.

“…The chemical composition of these essential oils varies due to environmental factors such as temperature, sunlight, and water availability; these factors can cause changes in nutrient metabolism, which directly impacts the compounds produced [10] . Some of the major compounds identified in this study have previously been found in essential oils extracted from other Myrtaceae species, including E. dysenterica , [11] Myrciaria pilosa , [12] and Myrcia eximia ; [13] they have also been shown to have biological activity.…”

The purpose of this study was to analyses the influence of seasonal variation on the chemical composition and antimicrobial, antioxidant and cytotoxicity activities of the essential oil (EO) extracted from the leaves of Eugenia pohliana. Chemical characterization of the samples -by gas chromatography-mass spectrometryfound 35 and 38 components for summer and winter, respectively, of the EO from E. pohliana leaves, totaling 47 different compounds. Analysis of antioxidant capacity (DPPH, ABTS and TAC) revealed that the summer EO showed greater free radical scavenging capacity than the winter. Similarly, the summer EO exhibited superior antimicrobial potential (MIC = 128 -512 μg/mL and MMC = 128 -1024 μg/mL, compared to the winter EO (128-2048 μg/mL and 256-2048 μg/mL, respectively). Results showed that both oils had a low potential to cause hemolysis. This study provides new scientific evidence on the influence of seasonality on the pharmacological properties of E. pohliana leaves and its potential for the development of herbal medicines.

“…The Caatinga is an exclusively Brazilian biome. It presents the potential for new therapeutic agents since its vegetation undergoes physiological adaptations to constant climatic variation (high temperatures and low rainfall index) (Costa, Gomes, et al, 2020). Plants in this biome are commonly used by the community as natural medicines (Costa, Oliveira, et al, 2020).…”

Traditional packaging was developed to act as a protective barrier against the external environment. It was also designed to interact as little as possible with the packaged food (Khaneghah et al., 2018).However, these characteristics are no longer sufficient for new consumers, increasingly concerned and demanding environmentally friendly, healthy, sophisticated products that provide greater food security (Bhargava et al., 2020). Over the years, the need for new materials that extend the shelf life of food has emerged (Bhargava et al., 2020;Khaneghah et al., 2018). As a result, a new packaging concept emerged as active packaging.
