Gc. Onunkwo et al., STUDIES ON BRIDELIA-FERRUGINEA LEAVES .1. STABILITY AND HYPOGLYCEMIC ACTIONS OF THE LEAF EXTRACT TABLETS, PTR. Phytotherapy research, 10(5), 1996, pp. 418-420
The flavonoid content of 187.5 mg of Bridelia ferruginea leaf extract
was calculated to be approximately 0.015% based on rutin. There was no
significant difference (p = 0.05) in the mean values of flavonoids fo
r the tabletted and untabletted extract, The moisture adsorption of th
e crude drug tablets was of Vander Waals type. The tablets showed a ve
ry long shelf life of about 96 years. A 25 mg/kg of B. ferruginea tabl
et lowered the blood glucose level of normal healthy rabbits by about
40%.
