Background & Aim: considering the use of Beberis vulgaris in traditional medicine as a blood sugar depressant, in this study, the effect of Beberis vulgaris extracts were investigated on the level of insulin secretion from islets isolated of langerhans in male mice. Methods: This experimental study was carried out on 90 adult male mice, NMARI strains weighing 20-25 g. Pancreatic islets from normal mice were isolated by collagenase digestion method. Then the aqueous and hydro-alcoholic extract of Beberis vulgaris at 0.05, 0.1, and 1 mg/ml concentrations and glyburide at 1 and 10 μM concentrations were applied on islets isolated in three different concentration of glucose solution (2.8, 5.6 and 16.7 mM). Insulin secretion from hand-picked islets were evaluated in the static incubation system. The level of Insulin secretion was measured by the ELISA insulin kit. Data were analyzed with variance analysis. Results: Insulin secretion was significantly increased at 16.7 mM glucose concentration in comparison with 2.8 and 5.6 mM glucose concentration (p<0.05). Incubation of pancreatic islets isolated at 2.8 and 5.6 mM glucose concentration and low concentrations of extract (0.05 and 0.1mg/ml) significantly increased the insulin secretion (p<0.05). Glyburide at 10 μM concentration was more effective than aqueous and hydro alcoholic extract of Beberis vulgaris at 16.7 mM glucose. Conclusion: The present study supported the anti-diabetic effect of Beberis vulgaris extracts in vitro with low glucose concentration and it suggests that one of the anti diabetic mechanisms of this plant is via pancreatic islets.
