Purpose: To determine the antidiabetic, antioxidant and anti-hyperlipidemic effects of aqueous leaf extract of Artemisia argyi (Asteraceae) in alloxan (ALX)-induced diabetic rats. Experimental: Soxhlet apparatus was packed with grinded leaves of A. Argyi and subjected to extraction by double distillation using water as running solvent for 4 - 5 h. Male albino Wistar rats weighing 150 ± 10 g were used in this study. Diabetes was induced in overnight-fasted rats via intraperitoneal administration of freshly prepared 10 % alloxan solution at a dose of 186.9 mg/kg. Serum glucose (Glc), high-density lipoprotein cholesterol (HDL-c), triglycerides (TGs) and total cholesterol (TC) were evaluated using Randox assay kits. Serum reduced glutathione (GSH) was assayed using a slight modification of a previously reproted procedure, while histological examination was carried out microscopically after hematoxylin and eosin staining. Results: Oral administration of aqueous extract of Artemisia argyi significantly reduced ALX-induced increases in glycosylated hemoglobin and blood glucose, but significantly increased total protein, hemoglobin, insulin, and C-peptide levels (p < 0.05). Administration of the extract also led to a significant upsurge in non-enzymic antioxidants i.e. ceruloplasmin, GSH, vitamin E and vitamin C. The extract produced a hypolipidemic effect by significantly reducing total cholesterol (TC) and serum TGs. The hypoglycemic and hypolipidemic effects of the extract were dose-dependent (p < 0.05). Histological examination of the pancreas revealed that the extract protected the integrity of beta cells in ALX-induced diabetic rats. Conclusion: These results indicate the beneficial effects of Artemisia argyi against diabetes mellitus. Thus, Artemisia argyi may be useful in the management of diabetes mellitus.
