Inhibitory effect of CBD on α-glucosidase activity at concentrations of 10, 19, 38, 76, 152, 304, 608, and 1216 μM. Acarbose (19, 152, and 608 μM) was used as a positive control. Each sample was tested for three times, each in three replicates (n = 3). A p-value < 0.001 (***) or 0.0001 (****) was considered as statistically significant between the control and experimental groups
