Table 1. IC₅₀ for α-glucosidase and α-amylase of SW, SG and CC, extracted by different methods.

Each data point represents the mean of three replicates ± SEM. Mean values in each column, in each cinnamon varieties followed by the same letter, are not significantly different (p ≥ 0.05) by Tukeys multiple range comparison tests.^a
