a% α-glucosidase inhibitory activity of crude acetone extracts of ten South African Ficus species (0.5 mg/ml) and control (acarbose) (0.02 mg/ml). Results expressed as % mean ± SEM (n = 9).
b,c.No significant difference between extracts with same value, but significant difference p<0.05 between different values.
