a Average of three analyses (± standard deviation (SD)); b acarbose was used as a reference compound with IC50 value 294.4 ± 11.4 μg/mL. All values correspond to mean values ± SD of three replicates. Values with different letters (i–v) indicate statistically significant differences among groups at p < 0.05 by one-way ANOVA.
