STUDIES ON COMPONENTS WITH ANTIHYPERGLYCEMIC EFFECT OF MOMORDICA CHARANTIA L. POLYSACCHARIDES / 营养学报

ABSTRACT

Objective To investigate the antihyperglycemic effect and the most effective com-ponent of Momordica charantia L. and its mechanism. Method Water-extracted and alkali-extracted Momordica charantia L. polysaccharides with different molecular weight on streptozotocin induced diabetes mellitus mice were carried out. The antihyperglycemic mechanism was preliminarily analyzed. Results Alkali-extracted Momordica charantia L. polysaccharides could lower blood sugar,improve glucose tolerance and increase the content of hepatic glycogen significantly at the dose of both 200 and 400mg/kg bw. The content of fructosamine was also lowered. Conclusion The component of alkali extracted Momordica charantia L polysacchaides with maximal molecular weight possessed the best antihyperglycemic effect.
