SUMMARY:The aim of this study was to evaluate the nutritional quality, phenolic compounds, fatty acid and antioxidant activity in vitro as well as a toxicological screening of A. muricata seed oil in vivo. The chemical composition and quantification of phenolic compounds were determined by the Adolfo Lutz Institute normative. The antioxidant activity was evaluated by DPPH, FRAP and ABTS methods. The oil was extracted by chloroform/ methanol and precipitated crude (AmPtO) and supernatant oils (AmSO) were obtained. The fatty acid profile was evaluated by gas chromatography and total compounds by HPLC-DAD. BALB/C mice received AmPtO and AmSO (0.5 and 1.0mL·Kg -1 ) for 14 days. Toxicity parameters were assessed. The major fatty acids in the oil were oleic (39.2%) and linoleic (33%). HPLC-DAD suggested the presence of acetogenins (annonacin: 595 [M-H] -), with a greater presence in AmPtO. The AmPtO group showed toxicity, which may be related to the acetogenin content in AmPtO. The AmSO group showed no toxicity and this oil has potential for food or medicinal use.
KEYWORDS:Acetogenins; Annona muricata seeds; Annonacin; Linoleic acid; Oleic acid RESUMEN: Potencial del aceite de Annona muricata L.: Caracterización nutricional y fitoquímica asociada con no toxicidad. El objetivo de este estudio fue evaluar la calidad nutricional, compuestos fenólicos, ácidos grasos, actividad antioxidante in vitro y evaluación toxicológica del aceite de las semillas de la Annona muricata. La composición química y los compuestos fenólicos se determinaron de acuerdo con las normas del Instituto Adolfo Lutz y la actividad antioxidante por métodos de DPPH, FRAP y ABTS. El aceite fue extraído con cloroformo/metanol obteniéndose un precipitado crudo (AmPtO) y un aceite sobrenadante (AmSO). El perfil de ácidos grasos fue evaluado por cromatografía gaseosa y los compuestos fitoquímicos mediante HPLC-DAD. BALB/C recibieron AmPtO y AmSO (0,5 y 1,0 mL·kg
