Studies onBridelia ferruginea Leaves (1). Stability and Hypoglycaemic Actions of the Leaf Extract Tablets

Abstract

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 for the tabletted and untabletted extract. The moisture adsorption of the crude drug tablets was of Vander Waals type. The tablets showed a very long shelf life of about 96 years. A 25 mg/kg of B. ferruginea tablet lowered the blood glucose level of normal healthy rabbits by about 40%.

Stability of Cough Linctus (Streptol) Formulated from Named Medicinal Plant Extracts

“…[9][10][11] These determinations were carried out by checking the absorbance of graded concentrations of Streptol syrup at the wavelength of 291 nm established as the wavelength of maximum absorption for the marker compound GB-1. The active drug in Streptol was calculated based on GBI, since Garcinia kola seed extract constitutes about 80% of the active drug.…”

“…9,12) Three relative humidity ovens were set at 30°C, 50°C, and 70°C. The atmosphere inside each oven was maintained at 75% RH using saturated NaCl solution.…”
