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

Epilepsy & 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.

Selected Properties ofAraucaria AngustifoliaandAraucaria AraucanaSeed Protein

International Journal of Food Properties, 2011
Araucaria angustifolia and Araucaria araucana are coniferous trees with large and nutritious seeds. The structure and nutritional properties of the proteins of these seeds were studied. About 70% of the proteins of the gametophyte were soluble in distilled water, although their solubility decreased drastically in raw seed flour.
