  1. a% α-amylase inhibitory activity of crude acetone extracts of ten South African Ficus species (1 mg/ml) and control (acarbose) (0.04 mg/ml). Results expressed as% mean ± SEM (n = 9). b,c,dNo significant difference between extracts with same value, but significant difference p<0.05 between different values.
