Effect of different fractions of Swertia chirayita on the blood sugar level of albino rats.
A 95% ethanol extract and four fractions of Swertia chirayita were tested for blood sugar lowering activity in rats when given orally at 250 mg/kg. The hexane fraction caused maximum lowering although the ethanol extract was clearly active. Of the four dose levels of the hexane fraction tested, 250 mg/kg was found to produce the optimum effect and 300 mg/kg did not evoke a better response. The optimum dose produced significant lowering of blood sugar in fed, glucose-loaded and tolbutamide-pretreated animal models, but not in fasted rats.
