Table 4 Effective concentration causing 50% antioxidant ability (IC50 values) of aqueous extract of different parts of ripe African star apple fruit on inhibition of FeSO4 and SNP-induced lipid peroxidation in rat’s pancreas

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

Sample FeSO4-Induced lipid peroxidation (mg/ml) SNP-induced lipid peroxidation (mg/ml)
Pulp 0.54 ± 0.08a 0.63 ± 0.14a
Cotyledon 0.64 ± 0.17b 0.89 ± 0.13b
Seed coat 0.68 ± 0.15b 0.91 ± 0.15b
Pulp coat 0.34 ± 0.07c 0.49 ± 0.11c
EDTA 0.48 ± 0.04a 0.32 ± 0.10d
  1. The IC50 (effective concentration causing 50% antioxidant 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). Positive control: EDTA (Ethylenediaminetetraacetic acid)
