Antiglycation and antioxidant properties of Momordica charantia
Diabetes mellitus is a multifactorial disorder characterised by hyperglycaemia and leads to complications. These complications are caused by advanced glycation endproducts (AGEs) that form through protein glycation as a consequence of hyperglycaemia. A diversity of plants are utilised worldwide as t...

Diabetes mellitus is a multifactorial disorder characterised by hyperglycaemia and leads to complications. These complications are caused by advanced glycation endproducts (AGEs) that form through protein glycation as a consequence of hyperglycaemia. A diversity of plants are utilised worldwide as traditional medications for the treatment of diabetes mellitus, particularly in developing nations. A considerable quantity of literature has been published on Momordica charantia (MC) as a potent folk medicine for diabetes mellitus. The aim of this study was to investigate the antiglycation and antioxidant effects of HWE and CWE of MC on protein glycation.
