Fig. 6From: Antidiabetic activity, glucose uptake stimulation and α-glucosidase inhibitory effect of Chrysophyllum cainito L. stem bark extractThe effect of C. cainito extract (CE) on α-glucosidase activity. Values are expressed as mean ± S.E.M. of three separate experiments. Acarbose was used as positive control. Panel a and b are results from α-glucosidase inhibitory activities of C. cainito and acarbose, respectively. The calculated IC50 of the extract was 1.20 ± 0.09 μg/ml, whereas that of acarbose was 198.17 ± 4.74 μg/mlBack to article page
