This study aimed to characterise the physicochemical properties of the samples, including pH, total soluble solids, total titratable acidity, moisture content, ash, and mineral composition determined by atomic absorption spectroscopy. Major bioactive compounds, including vitamin C, organic acids, carotenoids, chlorophylls and derivatives, and phenolic compounds, were determined by liquid chromatography. The antioxidant potential was examined using ABTS and DPPH, antimicrobials (bacteria and fungi), biofilm inhibition (bacteria), and the haemolytic activity of Calathea lutea and Calathea inocephala leaves was evaluated. C. lutea showed high iron (2930.0 mg\/100 g DW), vitamin C (4.6 mg\/100 g DW), and tartaric acid (722.3 mg\/100 g DW). C. inocephala showed high lutein (83.5 mg\/100 g DW) and pheophytin b (177.5 mg\/100 g DW). Major phenolics included caffeic acid (16,996.3 mg\/100 g DW). Extracts at 1 mg\/mL inhibited multidrug resistance in Enterococcus faecalis and Enterococcus faecium and showed strong antibiofilm activity against Listeria monocytogenes. The antioxidant activity was 4.6 mmol TE\/100 g DW in the DPPH method, and the compound was haemocompatible at concentrations below 600 \u00b5g\/mL. These findings highlight its biotechnological potential and importance for sustainable community use.<\/jats:p>","DOI":"10.3390\/antiox15030274","type":"journal-article","created":{"date-parts":[[2026,2,24]],"date-time":"2026-02-24T10:14:44Z","timestamp":1771928084000},"page":"274","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Functional Evaluation, Antioxidant, Antimicrobial, Antibiofilm, and Haemolytic Capacity of Calathea lutea (Bijao) and Calathea inocephala (Shutupipanga) Leaves"],"prefix":"10.3390","volume":"15","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\/0000-0003-0220-4990","authenticated-orcid":false,"given":"Arianna","family":"Mayorga-Ramos","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n Biom\u00e9dica (CENBIO), Facultad de Ciencias de la Salud Eugenio Espejo, Universidad UTE, Quito 170527, 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"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-2385-4016","authenticated-orcid":false,"given":"Lizbeth","family":"Alpusig-Guanoluisa","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\/0009-0001-5479-2969","authenticated-orcid":false,"given":"Felipe","family":"Rivera-Rueda","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\/0000-0001-9037-9306","authenticated-orcid":false,"given":"Johana","family":"Z\u00fa\u00f1iga-Miranda","sequence":"additional","affiliation":[{"name":"Centro de Investigaci\u00f3n Biom\u00e9dica (CENBIO), Facultad de Ciencias de la Salud Eugenio Espejo, Universidad UTE, Quito 170527, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8129-233X","authenticated-orcid":false,"given":"Carlos","family":"Barba-Ostria","sequence":"additional","affiliation":[{"name":"Escuela de Medicina, Colegio de Ciencias de la Salud Quito, Universidad San Francisco de Quito (USFQ), Quito 170901, Ecuador"},{"name":"Instituto de Microbiolog\u00eda, Universidad San Francisco de Quito (USFQ), Quito 170901, 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":"Centro de Investigaci\u00f3n Biom\u00e9dica (CENBIO), Facultad de Ciencias de la Salud Eugenio Espejo, Universidad UTE, Quito 170527, Ecuador"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"189","DOI":"10.31254\/phyto.2023.12307","article-title":"Exploring the Diverse Bioactive Compounds from Medicinal Plants: A Review","volume":"12","author":"Dar","year":"2023","journal-title":"J.
