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.

Plants synthesize a wide range of secondary metabolites, including phenolic compounds and terpenoids, which play key ecological roles and have relevant agro-industrial applications. The genus Baccharis, belonging to the family Asteraceae, is highly abundant in South America, particularly in Brazil, and has long been used in traditional medicine, supporting its neotropical origin. Given the growing interest in the species that compose this genus and, in their metabolites, the present study aimed to compile a structured database to support the identification of volatile compounds occurring in Baccharis species. A total of 158 volatile compounds were identified across 15 species, most of which belong to the subgenus Baccharis. Eleven compounds were observed that may serve as chemotaxonomic markers for the genus. The species most extensively studied over the past decade were B. dracunculifolia and B. trimera. Altogether, these findings highlight the metabolic potential of the Baccharis genus and point to new prospects for pharmaceutical and agro-industrial applications .

The Cerrado is Brazil's second largest biome and the most biodiverse savannah in the world. This biome has several phytophysiognomies, with many fruit trees. Among the trees of the Cerrado is the pequi tree (Caryocar brasiliense Camb.), with fruit known as pequi. The pequi is a fruit of great socio-economic and cultural importance for the region and for Brazil. In addition to its cultural and economic importance, pequi stands out for its rich chemical composition, containing carotenoids such as β-carotene, phytosterols, flavonoids, phenolic acids and tocopherols. These compounds have antioxidant, anti-inflammatory and hepatoprotective properties, as well as cardiovascular, neuroprotective and immunological benefits, reinforcing their functional and sustainable value in the Cerrado. The aim of this study was therefore to carry out a qualitative study of pequi through semi-structured interviews with rural producers in selected municipalities in the state of Minas Gerais, Brazil. It was clear that the farmers interviewed consume pequi frequently, especially during the harvest season. For the most part, the consumption of pequi by the interviewees is related to its flavour, aroma, beneficial health properties and cultural aspects. The producers recognise pequi as an environmentally friendly fruit and are concerned about deforestation in the Cerrado.

Maize (Zea mays) is a Poaceae of great global importance, which requires great technological investment, such as the Bt events, for herbivores populational control which can cause low productivity. This study aims to create a parallel between the metabolomics behavior of a maize variety and its isoline under the influence provoked by two-spotted spider mite damage. Differences in identified ions concentration and distribution were observed as coming from the monosaccharides, jasmonic acid and methyl jasmonate ionizations, metabolites that would be directly related to the induced defense, which showed higher concentration in the Bt maize leaves, clean and infested, and in the conventional infested maize leaves. Furthermore, other two ions, m/z: 391.018 and 217.012, were observed in higher concentrations in Bt maize leaves, clean and infested, and in the conventional infested maize leaves. With the obtained data, It was possible to conclude that the maize plants, both Bt and conventional, are capable of respond to damage provoked by two-spotted spider mite infestation, and the maize Bt plants it was an expressive response in comparison to its isoline.

Background: Alecrim-do-campo (Baccharis dracunculifolia) is a species of agroindustrial and medicinal relevance that has attracted increasing interest in recent years due to its distinctive chemical profile rich in bioactive compounds. In this context, the present study evaluated the efficiency of different extraction conditions for volatile compounds in alecrim-do-campo, aiming to contribute to the traceability of products that use this species as a source of metabolites. Methods: A 2³ factorial design was employed to assess the best conditions for extracting volatiles by headspace solid-phase microextraction (HS-SPME), using three different semipolar fibers (PDMS/DVB, DVB/CAR/PDMS and CAR/PDMS). Regarding the effect of the variation factors to which the samples were subjected, only the extraction time (min) had a significant effect on compound extraction using the CAR/PDMS fiber. Results: In total, 79 volatile compounds were detected using the three fibers, with CAR/PDMS (43 compounds) and DVB/CAR/PDMS (44 compounds) showing the highest diversity. The nature of this study is important for the industry because it optimizes the search for quality parameters in plant-derived products.
