“…O extrato EAC (Figura 1) apresentou apenas 2 picos (1 e 5 qual foi similar nos tempos avaliados de duas a cinco horas (Oliveira et al, 2017). O rendimento e a composição dos óleos essenciais extraídos diferem entre as partes da mesma planta (Sá et al, 2018) e entre espécies do mesmo gênero (Bin et al, 2022).…”

A Campomanesia adamantium, ou guavira, é nativa do Cerrado brasileiro e cresce naturalmente em solos pobres e condições adversas. Essa planta apresenta propriedades antimicrobiana, antiinflamatória, antitumoral, antioxidante, entre outras. Dos frutos, a polpa é a parte mais utilizada, restando casca e semente. Esses resíduos contêm compostos bioativos e têm potencial biológico que muitas vezes é subestimado. O estudo investigou os extratos vegetais e o óleo essencial da casca e da semente do fruto da guavira em relação à influência do solvente, composição química, compostos fenólicos, flavonoides e atividade antibacteriana. Utilizou-se seis solventes: água destilada, metanol 50%, etanol 70%, acetona 70%, hexano e acetato de etila e o óleo essencial foi extraído por hidrodestilação (três e cinco horas). O metanol produziu o maior rendimento (49%) para a semente, enquanto o etanol foi mais eficaz (41%) na extração da casca. O tipo de solvente interferiu no perfil cromatográfico e nos outros parâmetros, onde a acetona extraiu mais compostos fenólicos (3197,9 e 2840,3 mg GAE/ 100 g) e flavonoides (203 e 809 mg QUE/ 100 g), em casca e semente respectivamente. Houve ação bactericida pelo extrato hexânico da casca (MIC: 2000 µg/mL) para Staphylococcus aureus e S. pyogenes, e pelo extrato com acetato de etila da semente (MIC: 2000 µg/mL) para S. pyogenes. Óleo essencial da casca apresentou efeito bactericida para Klebsiela sp. (MIC: 450 µg/mL). A pesquisa indica potencial biológico do resíduo desse fruto, que pode ser melhor esclarecido com estudos complementares que investiguem a atividade antibacteriana dos constituintes individuais.

“…In the extraction of essential oils from fruit peels of 3 species of citrus (Citrus deliciosa, Citrus sinensis, and Citrus reticulata -Myrtaceae), was obtained 0.8% yield (Dias et al, 2020). Despite the apparent low yield, the EO industry is expanding and the discovery of new sources of EO is economically important due to the biological potential favored by the extraction of EO from underused waste and due to high market value (Bueno et al, 2021;Bin et al, 2022). Thus, the percentage of EO obtained from residues of the pulping of guavira is relevant, which are often discarded in the environment, generating an increase in waste.…”

The essential oil (EO) extracted from the peels and seeds of guavira (Campomanesia adamantium) was microencapsulated via complex coacervation between gelatin and gum arabic, followed by freeze-drying. This process aimed to reduce the volatility of the essential oil and protect bioactive compounds through the microcapsule wall. For process optimization, the influence of proportions of wall materials (gelatin: gum arabic ratios of 1:1, 1:2, 1:3, 2:1, and 3:1) and EO quantity (20% - 42.8%) on antioxidant capacity, morphology, and microencapsulation yield was measured using a central composite rotational design (CCRD). Additionally, the chemical composition and EO retention rate in the microcapsules were assessed. Gelatin: gum arabic ratio of 1:2 and EO quantity of 40.3% resulted in superior results, with the highest antioxidant capacity, a microencapsulation yield of 68%, and spherical morphology. Notably, the incorporation of a higher amount of EO led to an increase in the antioxidant capacity, with values reaching up to 99% equivalent to pure oil. All formulations maintained the same pure EO’s main constituents, including α-pinene, limonene, β-ocimene, and β-caryophyllene, indicated by gas chromatography coupled to mass spectrometry. Consequently, for the first time, EO microcapsules were successfully obtained from guavira residue, showing high microencapsulation yield and EO retention. This achievement adds sustainable value to residue normally discarded, which enables better use of residue generated by the food industry. Due to the preservation of its antioxidant capacity and enhanced retention of volatile compounds, these microcapsules promise applications in the food, pharmaceutical, and cosmetic industries, aligning with sustainability principles.

The Myrtaceae family is renowned for its rich diversity of bioactive metabolites with broad applications across various industries. This review comprehensively explores the chemical composition and biological activities of Neotropical species within the Myrtaceae family from 2011 to 2023. A total of 170 papers were analyzed, covering 148 species from 28 genera, with notable emphasis on Eugenia, Eucalyptus, Myrcia, and Psidium. Compounds with relative abundance exceeding 10% were tabulated to highlight the most significant volatiles for each genus. Our findings were cross‐referenced with previous reviews whenever feasible. Antioxidant, antibacterial, and antimicrobial activities emerged as the primary focus, collectively representing 41% of the studies, predominantly conducted in vitro. Additionally, we discuss less conventional approaches to essential oil studies in Myrtaceae species, underscoring avenues for future exploration. The investigation of essential oils from Myrtaceae holds promise for significant advancements in biotechnology, with potential benefits for the economy, environment, and human health. This review serves as a valuable resource for guiding future research strategies in this field.
