Abstract

Celosia argentea commonly known as cockscomb plant is widely used in folkloric medicine in the treatment and management of diabetes mellitus. The effect of methanolic extract of Celosia argentea var. cristata L. (CAVCL) leaves on blood glucose level, superoxide dismutase (SOD), catalase (CAT), alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) activities, and malondialdehyde (MDA) level were evaluated in diabetic rats. Five groups of male albino rats consisting of 5 animals each were used for the present study. They were grouped as normal control, diabetic control, diabetic administered with 250 and 750 mg/kg b.w C. argentea, and 5 mg/kg b.w glibenclamide. Diabetes was induced with alloxan monohydrate intraperitoneally at 120 mg/kg b.w. The control and diabetic groups were given distilled water and rat chow for 21 days. Blood glucose level of each group was estimated every week, and at the end of the experiment, SOD, CAT, MDA and serum ALP, and AST and ALT activities were assayed in the liver and serum respectively of the experimental animals. The results showed a significant increase (p < 0.05) in serum AST, ALP, and ALT activities and reduction in SOD and CAT activities compared with normal control groups. The extract at both doses significantly lowered the high levels of the serum enzymes and increased the level of CAT and SOD. These results indicate an anti-hyperglycemia and antioxidative protective effect of C. argentea leaves.

Highlights

Diabetes mellitus (DM) is a chronic metabolic disorder characterized by chronic hyperglycemia with impaired carbohydrate, protein, and fatty acid metabolisms arising from deficiencies in insulin secretion, action, or both (WHO 1999)
Growing evidence suggests that oxidative stress resulting from increased hyperglycemia plays a significant effect in the pathogenesis of DM
We investigated the anti-hyperglycemic effect of the methanolic extract of C. argentea leaves vis-à-vis antioxidative and hepatic protective effects

Summary

Introduction

Diabetes mellitus (DM) is a chronic metabolic disorder characterized by chronic hyperglycemia with impaired carbohydrate, protein, and fatty acid metabolisms arising from deficiencies in insulin secretion, action, or both (WHO 1999). It is characterized by increased hyperglycemia resulting from defective production or action of insulin, leading to several complications such as cardiovascular, renal, neurological, and ocular disorders (Erukainure et al 2013). C. argentea (family: Amaranthaceae) is a broad leafy vegetable commonly known as quail grass, feather cockscomb, and Lagos spinach. C. argentea decoction is demonstrated in folkloric medicine in the treatment of diabetes, there are, few scientific studies to evaluate its antidiabetic property. This study, is designed to further validate the hypoglycemic and antioxidant properties of this plant
