Each value represents mean ± SEM; n=6 for each treatment. ^aCompared to the negative control, ^ccompared to CALE 200mg/kg, ^βcompared to baseline blood glucose level, and ^µcompared to the blood glucose level at 30 minute. ¹p < 0.05, ²p < 0.01, and ³p < 0.001. CALE = Calpurnia aurea leaf extract, DW = distilled water, and GLC = glibenclamide. Time refers to time after oral glucose loading.
