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.

The Annonaceae family is widely distributed in subtropical and tropical regions. Several species of this family are known for their pharmacological and beneficial properties to human health, mainly attributed to flavonoids. The objective of this work was to carry out an integrative review in order to identify the main flavonoids found in some plant parts belonging to the Annona genus: araticum tree (Annona crassiflora Mart.), graviola tree (Annona muricata), atemoya tree (Annona cherimolia Mill × Annona squamosa L.), pinha tree (Annona squamosa), bananinha tree (Annona leptopetala), and marolinho tree (Annona coriacea). Only articles published between the years 2016 to 2021 that answered the guiding question were considered, in order to obtain recent data. Then, search strategies were designated for each database used: Science Direct, CAPES Periodicals, and Scielo. Most of the studies retrieved from the databases are related to fruits. The results showed that the number of flavonoids identified varies according to the analytical methodology used to identify and quantify the compounds. Quercetin was the most commonly found compound in all fruits of the Annona genus studied, and epicatechin, rutin, and kaempferol were also found to a lesser extent. The presence of these compounds in Annona makes the fruit promising, with potential applicability in the pharmaceutical and food industry.

The baru (Dipteryx alata Vog.), a fruit native to the Cerrado biome, is well-known for its almonds, which are extensively exploited and exported. Unfortunately, the remaining parts of this fruit are often discarded. This study investigates the fixed chemical constituents of the baru, including the bark, pulp, endocarp, and almonds, using the PS–MS technique in positive and negative ionization modes. Notably, this research presents the first chemical profile of baru almonds in both their raw and roasted states. The analysis identified 57 compounds reported for the first time in a baru and 24 common compounds. The majority of these compounds are classified as flavonoids. In both ionization modes, the peel exhibited a higher proportion of phenolic compounds, although the chemical compounds varied among the peel, pulp, almond, and endocarp. These findings highlight the perspective of bioeconomy and biotechnology. By staggering baru fruit production alongside extractivists, we can optimize the utilization of all parts of the fruit. Furthermore, given the knowledge of the biological properties of flavonoids and the baru composition, we recommend additional studies to analyze their potential in preventing chronic non-communicable diseases.

The objective of this article is to present the importance of the Cerrado in the ecological and social cohesion of the country, as it is the second largest biome in Brazil and covers approximately 23% of the country. Its magnitude is so great that it makes it the second largest floristic group in the country. Brazil is a country of extraordinary biodiversity, with a wide variety of organisms present in all biomes, especially the Cerrado, which has been devastated by human actions. The Brazilian Savannah is one of the most strategically important regions in the world, mainly for agriculture, crop irrigation, mining, power generation, and the supply of people and animals. Rich in its biodiversity, it provides several essential ecosystem resources to the planet. The destruction of the Cerrado can lead to the loss of species and ecosystem services, negatively impacting the planet. It is extremely important that measures are taken for the preservation of this biome. The protection and preservation of this valuable biome is in line with some of the Sustainable Development Goals. Goal 2 - Zero Hunger and Sustainable Agriculture, is based on the principle of eradicating hunger, achieving food security and better nutrition through the promotion of sustainable agriculture. The proposal is that this goal can be achieved by 2030. Based on the numerous scientific records that prove the nutritional potential of the fruits of the Cerrado, enabling better nutrition for its consumers, it is necessary to encourage the sustainable cultivation and consumption of its fruits, perpetuation of the native trees of the Cerrado that provide not only nutritional benefits, but environmental, social and economic benefits.

The growth of the world population intensifies the demand for alternative sources of protein, making it essential to ensure food security. In this context, fruits and by‐products of plant origin stand out as alternatives for the development of new products rich in sustainable food proteins, capable of combining health benefits and waste valorization, in accordance with the principles of the circular economy. This study aimed to conduct an integrative review of innovative extraction techniques and enzymatic hydrolysis applied to the concentration of proteins from vegetable residues. Only articles published between the years 2020 and 2024 were considered that respond to the guiding question: What are the emerging methods used in the extraction of proteins and the obtaining of protein hydrolysates that maximize protein yield and produce hydrolysates with better functional and nutritional characteristics from plant‐based products? Subsequently, search strategies were developed for each chosen database: ScienceDirect, Scielo, PubMed, and Web of Science. In this way, data were compiled that highlighted and emphasized the innovative aspects of plant protein hydrolysates, aiming for their potential application in the food, cosmetics, and pharmaceutical industries.
