IC25 and IC50 (μg/mL) values found in the antioxidant activity, α-glucosidase, hemoglobin oxidation, and hemolysis assays of Saco sweet cherry extracts.
| Extract | DPPH• | •NO | O2•− | α-Glucosidase | Hemoglobin Oxidation | Hemolysis |
|---|---|---|---|---|---|---|
| Total extract | 21.88 ± 0.32 | 33.72 ± 0.89 | 41.68 ± 0.72 | 53.15 ± 1.32 | 34.29 ± 0.88 | 28.71 ± 0.73 |
| Colored fraction | 31.39 ± 0.60 a | 47.44 ± 0.67 a | 16.58 ± 0.27 (IC25) | 142.02 ± 1.17 a | 33.86 ± 0.70 | 9.44 ± 0.48 |
| Non-colored fraction | 210.86 ± 0.86 a,b | 167.96 ± 0.92 a,b | 69.40 ± 1.22 a,b | 456.19 ± 3.74 (IC25) | 155.13 ± 1.45 a,b | 48.31 ± 1.07 a,b |
Values are expressed as mean ± standard deviation of three assays concerning the antioxidant capacity against 1,1-diphenyl-2-picrylhydrazyl, nitric oxide and superoxide radicals (DPPH•, •NO and O2•−, respectively), α-glucosidase inhibitory activity, hemoglobin oxidation and hemolysis. IC25: 25% inhibitory concentration. a Significant result (p < 0.05) is indicated as vs. total extract. b p < 0.05 is indicated as vs. colored fraction.
