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

Sample	α-amylase inhibitory activity (mg/ml)	α-glucosidase inhibitory activity (mg/ml)
Pulp	1.46 ± 0.16^a	1.48 ± 0.17^a
Cotyledon	3.96 ± 0.59^b	2.29 ± 0.35^b
Seed coat	4.16 ± 0.62^c	1.79 ± 0.25^c
Pulp coat	1.39 ± 0.14^d	1.35 ± 0.13^d
Acarbose	1.20 ± 0.08^e	1.55 ± 0.19^c

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)
