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 fl owers 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 fl ower 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 signifi cant (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.
Background and Aim:Momordica charantia Linn. is traditionally used as a medicine for diabetes. The present investigation was aimed to formulate and evaluate transdermal patchesof Momordica charantia Linn.Materials and Methods:The transdermal films containing the herbal drug component fractionated fromethanolicextract of M. charantia fruits were prepared by using hydroxy propyl methyl cellulose as a polymer. The films were evaluated for folding endurance, thickness, weight variation, drug contents and in vitro diffusion studies and in vivo parameterslike acute and sub-acute antihyperglycemic activity in diabetic rats, biochemicalstudies, skin irritation in rats and stability studies.Result and discussion:The weightof transdermal patches of M. charantia (2 cm2; 10 mg/patch) and was found to be 0.03 gm.Thickness of patches of M. charantia (2 cm2; 10 mg/patch) was found to be satisfactory. The percentage release of active constituents from transdermal patches of M.charantia (2 cm2; 10 mg/patch) was found to be 47.59% in 10% hydroalcoholic phosphate buffer pH 7.4 at the end of 6 h.The transdermal route exhibited negligible skin irritation and in vivo results revealed that the patches successfully decrease the blood glucose level.Conclusion:From the results, we concluded that the well-known herbal drug M. charantia Linn. have been found to be effective for diabetes through modern pharmaceutical formulation techniques.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
