This study aimed to report the occurrence of this species in a Brazilian Cerrado area, evaluate its hydroethanolic extract, and determine its antioxidant and acetylcholinesterase inhibitory activities. <em>D. spathularia</em> mushrooms (150 g) were collected, and the hydroethanolic extract was prepared. Phytochemical screening was performed using colorimetric tests. Antioxidant activity was assessed by the reduction of the DPPH free radical, and acetylcholine inhibition was evaluated using <em>Electrophorus electricus</em> type VI enzyme. Twelve groups of phytocompounds were identified. The antioxidant activity, measured by DPPH reduction, showed an IC₅₀ of 10.95 µg mL^-1, and acetylcholinesterase inhibition demonstrated a result of 68.37%.</p> Guilherme Henrique Marques de Oliveira Antonio Carlos Pereira de Menezes Filho Matheus Vinícius Abadia Ventura Elizabete Nunes da Rocha Copyright (c) 2024 Guilherme Henrique Marques de Oliveira, Antonio Carlos Pereira de Menezes Filho, Matheus Vinícius Abadia Ventura, Elizabete Nunes da Rocha https://creativecommons.org/licenses/by/4.0/ 2024-11-25 2024-11-25 2 1 1 6 10.14295/cerrado.v2i1.707 https://periodicos.cerradopub.com.br/cerrado/article/view/708 <p><em>Lactuca sativa</em> is a widely distributed <em>oleracea</em> species, commonly used in various Western and Asian cuisines. This study aimed to evaluate the initial development of <em>L. sativa</em> cv. Psique by applying different concentrations of the commercial biostimulant and bioactivator Vitakelp (mL/L^-1) and assessing total fresh weight, total dry mass, root length, and aerial part length of seedlings in two foliar application periods. In the first application, increases were observed in total fresh mass, total dry mass, and aerial part length. In the second application, positive increments were found in total dry mass and aerial part length. The commercial product Vitakelp showed good improvements in the initial development of <em>Lactuca sativa</em> seedlings at different concentrations, especially between 2-6 mL/L^-1.</p> João Vitor Nogueira de Souza Antonio Carlos Pereira de Menezes Filho Matheus Vinícius Abadia Ventura Copyright (c) 2025 João Vitor Nogueira de Souza, Antonio Carlos Pereira de Menezes Filho, Matheus Vinícius Abadia Ventura https://creativecommons.org/licenses/by/4.0/ 2024-11-29 2024-11-29 2 1 7 12 10.14295/cerrado.v2i1.708
