Figure 1. Effect of the active fraction of ethanol extract of R. arboreum flowers on blood glucose (mM/L) and plasma insulin (µU/mL). NC, normal control; DC, diabetic control; DAF1, diabetic rats administered active fraction (200 mg/kg); DAF2, diabetic rats administered active fraction (400 mg/kg); DG, diabetic rats administered glibenclamide; “*” represents the significant (P<0.01) change as compared to NC and “**” represents the significant (P<0.001) and “***” represents the significant (P<0.000 1) change as compared to DC.
