Aim: The objective of this study was to assess in rats the antidiabetic effects (i.e. reduction of hyperglycaemia and hypertriglyceridaemia) of trans ‐dehydrocrotonin ( t ‐DCTN), a bioactive diterpene isolated from the popular medicinal plant Croton cajucara . Methods: Hyperglycaemia was induced by intraperitoneal injection of streptozotocin (STZ) and hypertriglyceridaemia by oral administration of ethanol in rats. The blood glucose levels were measured by the glucose oxidase method using commercially available enzyme kits. Results: Treating rats with t ‐DCTN (50 mg/kg) significantly reduced STZ‐induced increases in blood glucose levels as well as ethanol‐induced increases in blood triglycerides. Conclusion: The results suggest that t ‐DCTN has an antidiabetic potential that warrants further research on its mechanism and clinical significance.
