[The hypoglycemic effects of crude polysaccharides extract from Momordica charantia in mice].

ABSTRACT

OBJECTIVE: In order to study the hypoglycemic effects of crude polysaccharides extract from Momordica charantia in normal and diabetic mice. METHODS: Oral glucose tolerance test was carried out in 24 normal mice, CPS was orally administered in experiment group at 1 g/kg BW. 80 diabetic mice (type 1 and type 2 diabetic model) were divided into two groups randomly, CPS was administered at ad lib and fasted condition in experiment group at 1 g/kg BW, blood glucose was measured at different time. RESULTS: In normal mice, after administered glucose (3g/kgBW) the blood glucose level of experiment group at 0.5, 1 h was significantly lower than that of control group (16.4% and 16.5% lower than control group respectively, P < 0.05 and P < 0.01). In diabetic mice, the fasted and ad lib blood glucose after administering CPS orally 2h, 4h were lower than that of control group (P < 0.05 and P < 0.01 respectively). CONCLUSION: CPS can improve OGTT in normal mice, and has significant hypoglycemic effect in two types diabetic mice.
