This integrative review aims to identify the main flavonoids present in some species of the Myrtaceae family. Studies published between 2016 and 2022 were selected, specifically those which were fully available and written in Portuguese, English, or Spanish, and which were related to the fruits araçá (Psidium cattleianum), cambuí (Myrciaria floribunda), gabiroba (Campomanesia xanthocarpa), jabuticaba (Plinia cauliflora), and jambolan (Syzygium cumini). Scientific studies were gathered and selected in Google Scholar, Scielo, and Science Direct indexed databases, out of which 14 were about araçá, 7 concerned cambuí, 4 were about gabiroba, 29 were related to jabuticaba, and 33 concerned jambolan, when we observed the pre-established inclusion criteria. Results showed that the anthocyanins, such as cyanidin, petunidin, malvidin, and delphinidin, were the mostly identified class of flavonoids in plants of the Myrtaceae family, mainly relating to the purple/reddish color of the evaluated fruits. Other compounds, such as catechin, epicatechin, quercetin, and rutin were also identified in different constituent fractions, such as leaves, peel, pulp, seeds, and in developed products, such as jams, desserts, wines, teas, and other beverages. It is also worth noting the positive health effects verified in these studies, such as anti-inflammatory qualities for jambolan, antidiabetic qualities for gabiroba, antioxidant qualities for araçá, and cardioprotective actions for jabuticaba, which are related to the presence of these phytochemicals. Therefore, it is possible to point out that flavonoids are important compounds in the chemical constitution of the studied plants of the Myrtaceae family, with promising potential in the development of new products by the food, chemical, and pharmaceutical industries due to their bioactive properties.

In the 1990s and 2000s, several countries underwent important and significant changes in their universities. Likewise, in Brazil, due to the implementation of several government programs, there was an expansion of higher education and made possible a greater access to graduation. At the beginning of 2020, the world was threatened by COVID-19, several restrictive measures were implemented by government and private entities to contain the spread of the disease. In this way, Brazilian educational institutions were forced to temporarily suspend their in-person activities in order to promote social distancing. They soon found themselves in the challenge of implementing teaching methodological changes to continue the activities, in an emergency and remote way, since the outbreak of the disease did not stop within months and there was no prediction of when it would occur. This study aims to evaluate the performance of students at the Federal University of São João del-Rei at the Sete Lagoas campus in the discipline of Organic Chemistry, in the Food Engineering, Agronomic Engineering, Forestry Engineering and Interdisciplinary Biosystems courses in the two semesters of 2018 with 223 students and during the two semesters of the first year of emergency remote teaching (2020) with 337 students, drawing a parallel between them in order to raise the impacts of remote teaching for the discipline of Organic Chemistry.

Myrciaria floribunda também conhecida como cambuizeiro, é uma árvore nativa da Mata Atlântica brasileira e seus frutos apresentam potencial para o uso comercial. Este estudo objetivou avaliar o teor de compostos fenólicos totais e determinar o perfil fitoquímico dos frutos de cambuizeiros.

Dentre as muitas espécies de frutíferas nativas do Brasil que têm sido pouco exploradas, destaca-se a Myrciaria floribunda (também conhecida como cambuizeiro ou goiabeira), espécie com significativa variabilidade, que apresenta frutos de diferentes cores (laranja, vermelho e roxo) quando maduros. As características físico-químicas avaliadas foram peso do fruto (PF), peso da semente (PS), peso da polpa (PP), número de sementes (NS), diâmetro longitudinal (DL), diâmetro transversal (DT), formato (DL/DT), potencial de hidrogênio (pH), sólidos solúveis (SS), acidez titulável (AT) e razão (SS/AT); além disso, foram identificados os compostos orgânicos voláteis (COVs) de nove acessos de pomares de rumberry. As médias das variáveis PF,
