Introduction: Diabetes mellitus is an important risk factor for cardiovascular diseases; the possible uses of Spondias mombin and Curcuma longa rhizomes for the treatment of diabetes and cardiovascular disorders have become prevalent in our environment.
Aim: The present study attempts a Comparative assessment of the effects of methanolic extracts of Spondias mombin leaves and Curcuma longa rhizomes on serum lipid profile and electrolytes in alloxan induced diabetes in male wistar rats.
Methodology: 90 male wistar rats were randomly divided into 9 groups of 10 rats each. Diabetes was induced intraperitonially using alloxan at 200 mg/kg-bw. The different rat Groups were treated with extracts and glibenclamide orally for 42 days as follows: Group 1: untreated non diabetic; Group 2: untreated diabetic; Group 3: diabetic + low dose Spondias mombin; Group 4: diabetic + high dose Spondias mombin; Group 5: diabetic + low dose Curcuma longa; Group 6: diabetic + high dose Curcuma longa; Group 7: diabetic + low dose combined Spondias mombin and Curcuma longa; Group 8: diabetic + high dose combined Spondias mombin and Curcuma longa; and Group 9; diabetic + glibenclamide. Blood was collected on day 43 by cardiac puncture for determination of serum lipid profile and electrolytes.
Results: Compared to Group 2, total serum cholesterol, triglyceride, low density lipoprotein and electrolytes were significantly reduced while high density lipoprotein was significantly increased in all treated Groups (p<0.05). Compared to Groups 3 to 6, Groups 7 and 8 rats showed a significant reduction in total cholesterol, triglyceride and low density lipoprotein as well as electrolytes (p<0.05): however, high density lipoprotein was significantly increased (p<0.05).
Conclusion: Spondias mombin showed better hypolipidemic effects compared to Curcuma longa. However, results show that combined treatment with both extracts had better hypolipidemic effects than administration of individual extracts. Further research is recommended to evaluate the possible mechanism of action of these extract.
