Abstract
Comparative assessment of methanolic extracts of Spondias mombin leaves and Curcuma longa rhizomes on Blood Glucose and Glycosylated Haemoglobin using male wistar rats as models was attempted. 90 rats divided into 9 groups of 10 rats each were used. Groups: 1: Untreated non diabetic; 2: Untreated diabetic; 3: diabetic + low dose (200mg/kg/b.w) Spondias mombin; 4: diabetic + high dose (400mg/kg/b.w) Spondias mombin; 5: diabetic + low dose (500mg/kg/b.w) Curcuma longa; 6: diabetic + high dose (1000mg/kg/b.w) Curcuma longa; 7: diabetic + low dose combined (200mg/kg/b.w) Spondias mombin and (500mg/kg/b.w) Curcuma longa; 8: diabetic + high dose combined (400mg/kg/b.w) Spondias mombin and (1000mg/kg/b.w) Curcuma longa; and diabetic + (0.6mg/kg/b.w) glibenclamide. Diabetes was induced intraperitonially using alloxan at 200mg/kg. Treatments with extracts were orally and for 42days. Blood was collected on day 43 by cardiac puncture for determination of blood glucose and glycosylated haemoglobin. A significant decrease in blood glucose and glycosylated haemoglobin concentrations was observed in all the treated groups compared to group 2 (p< 0.05). Groups 7 and 8 rats showed a significant reduction in blood glucose and glycosylated haemoglobin compared to groups 3 to 6 (p< 0.05). Spondias mombin apparently showed better anti-diabetic effects compared to Curcuma longa as seen amongst Groups 3 and 4 rats compared to Groups 5 and 6 rats. Result suggest that combined treatment with Spondias mombin and Curcuma longa may possess better anti-diabetic effects compared to administration of each singly. We recommend further studies in this regard.Keywords: Spondias mombin, curcuma longa, diabetes mellitus, alloxan

Effect of methanolic extract of Spondias mombin leaves and Curcuma longa rhizomes on blood glucose: Table 1 shows the effect of methanolic extract of Spondias mombin leaves and Curcuma longa rhizomes on blood glucose concentration in male wistar rats
Compared to Group 2 rats, administration of extracts of Spondias mombin significantly reduced blood glucose in a dose dependent manner amongst Group 3 and 4 rats (p< 0.05). This effect of Spondias mombin is comparable to the effect of administration of glibenclamide observed amongst Group 9 rats
Summary
Comparative assessment of methanolic extracts of Spondias mombin leaves and Curcuma longa rhizomes on Blood Glucose and Glycosylated Haemoglobin using male wistar rats as models was attempted. 90 rats divided into 9 groups of 10 rats each were used. A comparison of the percentage reduction in blood glucose concentration at both low and high doses suggests that Spondias mombin is perhaps of marginally higher potency compared Curcuma longa; differences in blood glucose concentration was found to be significant (p
