Diversity of Secondary Metabolites of Araucaria Seed (Araucaria angustifolia (Bert.) O. Ktze) Residues

open access: yesEnsaios e Ciência C Biológicas Agrárias e da Saúde, 2022
A semente da Araucaria angustifolia (Bert.) O. Ktze é conhecida como pinhão e é considerada um alimento de alto valor nutricional. No consumo do pinhão, seu tegumento é descartado, gerando um resíduo que apresenta um processo lento de decomposição. Esse material é composto por três camadas de tecido: camada interna (endotesta), camada intermediária ...

Central action of Araucaria angustifolia seed lectin in mice [PDF]

open access: yesEpilepsy & Behavior, 2009
Possible central nervous system effects of the gymnosperm lectin from Araucaria angustifolia seeds were studied in seizure and open field tests. Male Swiss mice were administered saline (control), lectin (0.1, 1, and 10 mg/kg), flumazenil (1 mg/kg), or diazepam (1 mg/kg) intraperitoneally.
