Assessment of anti hyperglycemic fractions isolated from Albizia procera stem bark chloroform extract using STZ induced diabetic albino rats

Objective: The present Study was to identify more effective hypoglycemic fractions from chloroform extract of Albizia procera stem bark. Material and methods: Isolated fractions of Albizia procera stem bark chloroform extract were given individually to different batches of rats both normal (80 mg/kg of b.wt animals) and STZ induced diabetic rats (160mg/kg b.wt animals) after an overnight fast. The blood glucose levels were measured at 0, 1, 2, 3, 5 and 6 hours after the treatment. Fractions were also treated to STZ induced diabetic rats by chronically (80mg/kg b.wt). Results: The fractions E of Albizia procera stem bark chloroform extract was shown maximum blood glucose lowering effect in both normal and STZ diabetic rats with acute and chronic treatment. The other fractions are also showing hypoglycemic and antihyperglycemic activity, but the effect is significantly less than that of fraction E. The antihyperglycemic activity of fractions of Albizia procera stem bark chloroform extract was compared with the treatment of glibenclamide. Conclusion: The present data confirm the anti diabetic activity of Albizia procera in Indian traditional medicine for Diabetes mellitus treatment. The anti hyperglycemic action attributed to the presence of valuable flavonoids, terpinoids in the fraction E.
