Dacryopinax spathularia (Schwein) is an edible mushroom rich in specialized metabolism molecules. 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. D. spathularia 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 Electrophorus electricus 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%.

Initial development of Lactuca sativa (lettuce) using a biostimulant and bioactivator for hydroponic purposes

Lactuca sativa is a widely distributed oleracea species, commonly used in various Western and Asian cuisines. This study aimed to evaluate the initial development of L. sativa 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 Lactuca sativa seedlings at different concentrations, especially between 2-6 mL/L^-1.
