Effect of aqueous extract of Cyamopsis tetragonoloba Linn. beans on blood glucose level in normal and alloxan-induced diabetic rats.

Effect of feeding orally the aqueous extract of beans of Cyamopsis tetragonoloba was investigated on fasting blood glucose levels in glucose loaded, normal and alloxan-induced diabetic rats and compared with gliclazide, a reference drug. The aqueous extract of beans at 250 mg/kg body wt significantly lowered blood glucose levels in alloxan-induced diabetic rats within 3 hr of administration. Continued administration of the extract at the same dose daily for 10 days produced statistically significant reduction in the blood glucose levels while marginal activity was seen in normal and glucose-loaded rats.
