Table 5 Effective concentration causing 50% inhibitory ability (IC50 values) of α-amylase and α-glucosidase inhibitory activities of fruits parts

From: Starch composition, glycemic indices, antioxidant properties and carbohydrate hydrolyzing enzymes activities of African star apple fruit parts

Sample α-amylase inhibitory activity (mg/ml) α-glucosidase inhibitory activity (mg/ml)
Pulp 1.46 ± 0.16a 1.48 ± 0.17a
Cotyledon 3.96 ± 0.59b 2.29 ± 0.35b
Seed coat 4.16 ± 0.62c 1.79 ± 0.25c
Pulp coat 1.39 ± 0.14d 1.35 ± 0.13d
Acarbose 1.20 ± 0.08e 1.55 ± 0.19c
  1. The IC50 (effective concentration causing 50% inhibitory ability) were calculated using nonlinear regression analysis. Values represent mean ± standard deviation (n = 3). Values with the same letter within a column are not significantly different (p > 0.05)
