Antidiabetic Evaluation of Momordica charantia L Fruit Extracts

Journal Authors: 


To investigate hypoglycaemic, hypolipidaemic and pancreatic beta cell regeneration activities of Momordica charantia L fruits (MC). Alloxan induced diabetic rabbits were treated with methanolic and ethanolic MC extract. Effects of plant extracts and the drug, glibenclamide on serum glucose, lipid profile and pancreatic beta cell were determined after two weeks of treatment. Serum glucose and lipid profiles were assayed by kit methods. Pancreatic tissue histopathology was performed to study pancreatic beta cells regeneration. Momordica charantia extracts produced significant hypoglycaemic effects (p < 0.05). Hypolipidaemic activity of MC was negligible. Momordica charantia supplementations were unable to normalize glucose and lipid profiles. Glibenclamide, a standard drug, not only lowered the hyperglycaemia and hyperlipidaemia but also restored the normal levels. Regeneration of pancreatic beta cells by MC extracts was minimal, with fractional improvement produced by glibenclamide. The most significant finding of the present study was a 28% reduction in hyperglycaemia by MC ethanol extracts. To determine reliable antidiabetic potentials of MC, identification of the relevant antidiabetic components and underlying mechanisms is warranted.
