Abstract


 Les composés bioactifs des épices potentiellement antioxydant, hypoglycémiant et hypolipidémiant sont considérés comme des facteurs nutritionnels de choix dans la stratégie de prévention du syndrome métabolique (Smet). Le but de cette étude était d’évaluer les propriétés antihyperglycémiante, antihyperlipidémiante et antilipoperoxydative des extraits hydroéthanoliques (EHE) de trois épices locales : Aframomum aulacocorpus, Aframomum citratum et Aframomum daniellii. L’EHE d’A.daniellii a été plus actif pour l’inhibition des activités amylasique (99,19%) et invertasique (94,68%) comparé aux autres extraits (p<0,05) tandis que l’EHE d’A.aulacocorpus a significativement inhibé la lipase (93,33%). Les tests aigus ont montré que l’EHE d’A.aulacocorpus avait un effet antihyperlipidémiant important (77% ; p<0,05) alors que l’effet antihyperglycémiant était plus élevé avec l’EHE d’A.daniellii (78,48%) (p<0,05).
