Resumo: | Pequi (Caryocar sp.) is a fruit native to Brazil, widely found in the Cerrado and Amazon biomes, representing great socioeconomic importance for these regions. The nutritional and bioactive composition of this fruit is related to several health benefits, in addition to providing industrial and economic advances. Knowing this, the objective of this work was to determine the content of bioactive compounds in the fresh pulp and oil of pequi from the Cerrado and pequi from the Amazon. The analyses carried out to quantify the content of bioactive compounds in the samples were total phenolic compounds, total flavonoids and total phenolic acids, while the antioxidant capacity was determined by the DPPH, ABTS and FRAP methods. The fatty acid profile present in the oil samples was identified and quantified using gas chromatography (GC) and the carotenoid content of the samples using high-performance liquid chromatography (HPLC), content of vitamin A was also determined. Based on the results, the pulp and oil of pequi from Cerrado and pequi from Xingu presented the compounds β-carotene, α-carotene and β-cryptoxanthin, in which the majority compound was β-carotene; comparing the carotenoid profile of the two fruits, it was noted that the pulp and oil of Cerrado pequi had the highest β-carotene content and consequently total carotenoids. These results influenced the vitamin A content, where Cerrado pequi oil and pulp presented the highest levels; it was also possible to verify that the Cerrado pequi pulp has a higher oil yield, and that the main fatty acids found in the Cerrado pequi oil and the Xingu pequi oil were linoleic fatty acid (C18:2 – cis ( n6)), palmitoleic (C16:1), γ-linolenic (C18:3 (n6)), oleic (C18:1 – cis (n9)), tridecanoic (C13:0) and others in smaller quantities, being 98% unsaturated. Comparing the results of bioactive compounds, it can be observed that the hydrophilic extracts of the pulp and Cerrado pequi oil obtained the highest levels for the analyses of total phenolic compounds, ABTS, DPPH and FRAP, while the hydrophilic extract of pequi oil from Xingu showed higher results for total phenolic acids. In the lipophilic extracts, the lipophilic fraction of pequi from Cerrado oil was superior to pequi from Xingu for ABTS analysis, while the other results did not show significant differences. It was possible to verify that the hydrophilic extracts from the pulps achieved greater antioxidant capacity than the hydrophilic extracts from the oils, while in the lipophilic extracts the antioxidant capacity was greater for the oil, considering that the DPPH method proved to be the most efficient for all samples. Therefore, the pulp and oil of pequi from Cerrado and pequi from Xingu presented antioxidant potential attributed to the presence of bioactive and consequently therapeutic compounds, in which the oils demonstrate to be a good source of unsaturated fatty acids, with emphasis on pequi grown in the biome. closed for presenting the best results. |

A composição nutricional e bioativa deste fruto está relacionada a diversos benefícios a saúde, além de proporcionar avanços industriais e econômicos. Sabendo disso, o objetivo deste trabalho foi determinar o conteúdo de compostos bioativos da polpa in natura e do óleo do pequi do Cerrado e do pequi da Amazônia. As análises realizadas para quantificar o conteúdo de compostos bioativos das amostras foram compostos fenólicos totais, flavonoides totais e ácidos fenólicos totais, enquanto a capacidade antioxidante foi determinada pelos métodos de DPPH, ABTS e FRAP. Foram identificados e quantificados o perfil de ácidos graxos presentes nas amostras de óleo, através de cromatografia gasosa (CG), o teor de carotenoides das amostras utilizando cromatografia líquida de alta eficiência (CLAE) e o conteúdo de vitamina A. Com base nos resultados, a polpa e o óleo de pequi do Cerrado e pequi do Xingu apresentaram os compostos β-caroteno, α-caroteno e β-criptoxantina, em que o composto majoritário foi o βcaroteno; comparando o perfil de carotenoides dos dois pequis, notou-se que a polpa e o óleo de pequi do Cerrado apresentaram o maior teor de β-caroteno e consequentemente de carotenoides totais. Esses resultados influenciaram no conteúdo de vitamina A, onde o óleo e a polpa de pequi do Cerrado apresentaram os maiores teores; também foi possível verificar que a polpa de pequi do Cerrado possui um maior rendimento de óleo, e que os principais ácidos graxos encontrados no óleo de pequi do Cerrado e no óleo de pequi do Xingu foram o ácido graxo linoleico (C18:2 – cis (n6)), palmitoleico (C16:1), γ-linolênico (C18:3 (n6)), oleico (C18:1 – cis (n9)), tridecanoico (C13:0) e outros em menores quantidades, sendo 98% insaturados. Comparando os resultados de compostos bioativos, pode-se observar que os extratos hidrofílicos da polpa e do óleo de pequi do Cerrado obteve os maiores teores para as análises de compostos fenólicos totais, ABTS, DPPH e FRAP, enquanto o extrato hidrofílico do óleo de pequi do Xingu apresentou maiores resultados para ácidos fenólicos totais. Nos extratos lipofílicos, a fração lipofílica do óleo de pequi do Cerrado apresentou superioridade ao pequi do Xingu para a análise de ABTS, enquanto os outros resultados não apresentaram diferenças significativas. Foi possível verificar que os extratos hidrofílicos das polpas alcançaram maior capacidade antioxidante que os extratos hidrofílicos dos óleos, enquanto nos extratos lipofílicos a capacidade antioxidante foi maior para o óleo, tendo em vista que o método de DPPH demonstrou ser o mais eficiente para todas as amostras. Portanto, a polpa e o óleo de pequi do Cerrado e pequi do Xingu apresentaram potencial antioxidante atribuído a presença dos compostos bioativos e consequentemente terapêutico, em que os óleos demonstram ser uma boa fonte de ácidos graxos insaturados, tendo como destaque o pequi cultivado no bioma Cerrado por apresentar os melhores resultados.Universidade Federal de Mato GrossoBrasilInstituto de Ciências Exatas e da Terra (ICET) – AraguaiaUFMT CUA - AraguaiaEngenharia de Alimentos - CUAPertuzatti, Paula Becker7449261555135508http://lattes.cnpq.br/7449261555135508Assis, Renato Queiroz8734612822570355http://lattes.cnpq.br/8734612822570355Pertuzatti, Paula Becker7449261555135508http://lattes.cnpq.br/7449261555135508Araujo, Renata Lazara de6309359034853695http://lattes.cnpq.br/6309359034853695Abud, Cátia Oliveira Guimarães4850617173763035http://lattes.cnpq.br/4850617173763035Silva, Julia Correia2024-07-10T23:32:13Z2023-10-272024-07-10T23:32:13Z2023-10-20info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/datasetSILVA, Julia Correia.
