Fig. 1From: α-glucosidase and glycation inhibitory effects of costus speciosus leavesThe percent α-amylase and α-glucosidase inhibitions (%) of COS at varying concentrations. Data are indicated as mean percentage inhibition. Final concentrations of the extract used for amylase inhibitory assay were 1, 2, 3, 4, 5, 6.5 mg/ml and for glucosidase inhibitory assay were 50, 60, 70, 80, 100 μg/mlBack to article page
