Figure 2. Effects of methanol extract of N. sativa on (A–F) GI sucrose content after oral sucrose loading in type 2 diabetic rats.

Type 2 diabetic rats were fasted for 24 h prior to the oral administration of sucrose solution (2.5 g/kg body weight) in the presence (treated group) or absence of (control group) methanol extract of N. sativa (500 mg/kg body weight). The values are means and standard deviations represented by vertical bars (n=6). The mean values that are marked with an asterisk (*) were substantially different from those of respective type 2 diabetic control rats (*P<0.05 and **P<0.01) (this was derived from repeated-measures ANOVA and adjusted using Bonferroni correction).
