OBJECTIVE
To evaluate the antihyperglycemic property of Cinnamomum bejolghota (Buch.-Ham.) on streptozotocin induced type-2 diabetic rats.
METHODS
Oral glucose tolerance test level was measured at 0, 30, 60, 90 and 120 min after the administration of extract. The extract was orally administered once daily at two dose levels of 250 and 500 mg/kg for 15 d. The effect of methanolic extract of Cinnamomum bejolghota (MECB) on the divergence of body weights, blood glucose levels and the biochemical parameters viz., total cholesterol, high density lipoprotein, low density lipoprotein, triglyceride, aspartate transaminase, alanine transaminase, alkaline phosphatase were measured in an autoanalyzer. Histopathology of pancreas and in vivo antioxidative status was studied.
RESULTS
A significant increase in bodyweights and rapid decrease in hyperglycemic peak was experiential in animals treated with MECB. After 15 d treatment the total cholesterol, TG, low density lipoprotein level decreased and high density cholesterol level increased significantly. MECB reduced the levels of the elevated marker enzymes aspartate transaminase, alanine transaminase and alkaline phosphatase. MECB reduced the lipid peroxidation and improved the level of catalase and glutathione in liver. Histopathological studies of pancreas in diabetic and treated groups substantiate the cytoprotective action of extract.
CONCLUSIONS
It can be evident from the research work that Cinnamomum bejolghota (Buch.-Ham.) has potent antihyperglycemic activity and supports the in vivo antioxidative status.
