Abstract

Syzygium cumini leaves are used locally especially in Nigeria for the treatment \ management of diabetes mellitus and Alzheimer’s disease. This study was designed to investigate the effects of polyphenols extracted from Syzygium cumini l eaves on the occurrence of oxidative stress in the brain of rats with diabetes, which can trigger Alzheimer’s disease by determining both in vitro and in vivo c holinesterase, the antioxidant defense system, and the extent of oxidative damage. The effect of polyphenols extracted from Syzygium cumini leaves was investigated on in vitro c holinesterase. Thereafter, the extract (400 mg/kg body weight) of both free and bound polyphenols was administered orally to alloxan - induced rats, and the effect were monitore d on in vivo c holinesterase, superoxide dismutase, catalase, glutathione peroxidase, reduced glutathione, lipid peroxidation and hydroperoxides. The extract demonstrated inhibitory effects against in vitro c holinesterase. A significant reduction in the c ho linesterase activities increased the activities of superoxide dismutase, catalase, glutathione peroxidase, and reduced glutathione. A reduction in lipid peroxidation and hydroperoxide concentrations was observed in the brain of diabetic rats treated with p olyphenols extracted from Syzygium cumini leaves. This study suggests that the polyphenols of Syzygium cumini leaves have anti - Alzheimer and antioxidant boosters, as well as antiperoxidative activities. Therefore, the plant is recommended for both diabetic and Alzheimer’s disease patients worldwide
