This research aimed to evaluate the presence of bioactive compounds, as well as the antioxidant and antimicrobial activity of Miconia crenata, Grias neuberthii, Lacmellea oblongata, Pourouma cecprofiilia, and Annona edulis. Physical and chemical parameters, mineral content (atomic absorption), vitamin C, organic acid, carotenoids, chlorophylls, and phenols (liquid chromatography), antioxidant activity (ABTS, DPPH), and antimicrobial activity (against Candida albicans, Candida tropicalis, Escherichia coli, Staphylococcus aureus, and Streptococcus mutans) were determined. High concentrations of calcium, syringic acid, and antioxidant activity were found in the fruits of Miconia crenata; malic and caffeic acids in Grias neuberthii; citric acid, naringenin, and antioxidant activity in Lactuca oblongata; potassium, chlorogenic acid, and ferulic acid in Pourouma cecropiifolia; and tartaric acid and gallic acid in Annona edulis. Additionally, low antimicrobial activity was observed in M. crenata against E. coli (2.7 mg\/mL), G. neuberthii against S. aureus (10.3 mg\/mL), and L. oblongata against S. mutans (10.4 mg\/mL), C. albicans (20.8 mg\/mL), and C. tropicalis (20.8 mg\/mL). The results confirm that these Amazonian fruits are a relevant source of functional bioactive compounds, highlighting their potential for use in the food, pharmaceutical, and biotechnology sectors.<\/jats:p>","DOI":"10.3390\/antiox14080924","type":"journal-article","created":{"date-parts":[[2025,7,29]],"date-time":"2025-07-29T09:31:45Z","timestamp":1753781505000},"page":"924","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Lacmellea oblongata and Other Undervalued Amazonian Fruits as Functional, Antioxidant, and Antimicrobial Matrices"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4495-3500","authenticated-orcid":false,"given":"Elena","family":"Coyago-Cruz","sequence":"first","affiliation":[{"name":"Carrera de Ingenier\u00eda en Biotecnolog\u00eda, Universidad Polit\u00e9cnica Salesiana, Sede Quito, Campus El Gir\u00f3n, Av. 12 de Octubre N2422 y Wilson, Quito 170143, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5903-6735","authenticated-orcid":false,"given":"Gabriela","family":"M\u00e9ndez","sequence":"additional","affiliation":[{"name":"Carrera de Ingenier\u00eda en Biotecnolog\u00eda, Universidad Polit\u00e9cnica Salesiana, Sede Quito, Campus El Gir\u00f3n, Av. 12 de Octubre N2422 y Wilson, Quito 170143, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruth","family":"Escobar-Qui\u00f1onez","sequence":"additional","affiliation":[{"name":"Carrera de Ingenier\u00eda en Biotecnolog\u00eda, Universidad Polit\u00e9cnica Salesiana, Sede Quito, Campus El Gir\u00f3n, Av. 12 de Octubre N2422 y Wilson, Quito 170143, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco","family":"Cerna","sequence":"additional","affiliation":[{"name":"Carrera de Ingenier\u00eda en Biotecnolog\u00eda, Universidad Polit\u00e9cnica Salesiana, Sede Quito, Campus El Gir\u00f3n, Av. 12 de Octubre N2422 y Wilson, Quito 170143, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7620-9140","authenticated-orcid":false,"given":"Jorge","family":"Heredia-Moya","sequence":"additional","affiliation":[{"name":"Facultad de Ciencias de la Salud Eugenio Espejo, Centro de Investigaci\u00f3n Biom\u00e9dica (CENBIO), Universidad UTE, Quito 170527, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Duarte-Casar, R., Gonz\u00e1lez-Jaramillo, N., Bailon-Moscoso, N., Rojas-Le-Fort, M., and Romero-Benavides, J.
