OBJECTIVE
To investigate antidiabetic potential of alcoholic leaves extract of Alangium lamarckii (A. lamarckii) on streptozotocin-nicotinamide induced type 2 diabetic rats.
METHODS
Oral glucose tolerance test was done by inducing hyperglycemic state via administration of glucose in water (2g/kg). Single dose of alcoholic leaves extract of A. lamarckii (250 and 500 mg/kg, p.o.) were administered to normoglycemic, hyperglycemic rats. Type 2 diabetes was induced by single intraperitoneal injection of nicotinamide (110 mg/kg) followed by streptozotocin (65mg/kg). The study also included estimations of blood plasma glucose, lipid profile, liver glycogen, body weight and antioxidant status in normal and diabetic rats.
RESULTS
Admistration of alcoholic extract of A. lamarckii at two dosage 250 and 500 mg/kg, p.o. did not showed any significant change in blood glucose level of normoglycemic rats (P>0.05), whereas, oral glucose tolerance test depicted reduction in blood glucose level (P<0.05). The streptozotocin-nicotinamide induced diabetic rats, significantly decreased the blood plasma glucose level (P<0.001) comparable to glibenclamide (10 mg/kg), restored the lipid profile and showed improvement in liver glycogen, body weight and antioxidant status in diabetic rats.
CONCLUSIONS
Present finding demonstrated the significant antidiabetic activity of alcoholic leaves extract of A. lamarckii.
