Abstract
Background: Momordica Charantia (MC), widely cultivated around the world for
its medicinal and nutritional purposes, has been reported to have hypoglycemic
properties. Aim: This study was conducted to determine the effect of MC leaf
extract and anti-diabetic drug on oral glucose tolerance test (OGTT) in female
Sprague Dawley. Methods: Fifty apparently healthy female rats selected into 5
groups of 5 rats each were used for this study. The study was done in 2 stages:
Stage 1: Simultaneous administration of glucose, MC and/or perglim-2 (Groups:
A1-Control; B1-Glucose; C1- Glucose + MC; D1-Glucose + Perglim m-2 and E1-
Glucose, MC and Perglim m-2). Stage 2: Administration of glucose 45minutes
after MC and/or perglim m-2 had been administered (Groups: A2-Control; B2-
Glucose; C2-Glucose + MC, D2-Glucose + Perglim m-2 and E2-Glucose, MC
and Perglim m-2). In experimental rats that fasted for 18hours, fasting blood
glucose was determined before the commencement of the study. After oral
administration of glucose, MC and/or perglim m-2, blood glucose level was
monitored in the rats at time intervals of 0, 15, 30, 45, 60, 75, 90, 105 and
120minutes using Accu-chek glucometer. Result: The result showed that MC
and perglim m-2 demonstrated significant decrease (P>0.05) in the blood
glucose level of administered rats when compared with the control group in both
stages. Conclusion: Aqueous extract of MC leaves was observed to exhibit the
potential to correct impaired glucose tolerance although not for a long duration
of time.
