RESUMEN
Diabetes is a group of syndrome characterized by hyperglycemia, altered metabolism of lipids, carbohydrates and proteins, resulting in an increased risk of complications from vascular disease. The flowers of Woodfordia fruticosa (L.) Kurz, Lythraceae, have been used traditionally in the treatment of diabetes, dysentery, diarrhea, other bowel complaints, internal haemorrhages, in leucorrhoea and menorrhagia. Externally powdered flower is sprinkled over foul ulcers and wounds for diminishing their discharge and promoting granulations. In Konkan leaves are used in bilious sickness. W. fruticosa is also reported to have DNA topoisomerase inhibitor, antibacterial, antifertility, antipeptic ulcer, free radical scavenging, and hepatoprotective activity. W. fruticosa is a medicinal plant used to treat a wide range of disorder including diabetes. The present work investigates the effects of the WF in dexamethsone induced insulin resistance in mice. The results of animal study revealed that the extract at dose 100, 200 and 400 mg/kg was found to be significant (p<0.01) after 22 days of treatment. Further isolation studies afforded an anthraquinone glycoside, chrysophanol-8-O-β-D-glucopyranoside. Moreover further experiments will be required to identify their exact mechanism of action.
