| Methanolic extract | 15.67 ± 0.57a | 8.90 ± 0.83a |
| Aqueous extract | 0.70 ± 0.24c | 0.41 ± 0.10b |
| GI in vitro digested sour cherry samples | ||
| PG | 6.56 ± 0.11b | 0.05 ± 0.02b |
| IN | 0.02 ± 0.01c | 0.24 ± 0.02b |

Values are means of triplicate measurements ± standard deviations. Different letters in the same column represent significant difference at p < 0.05. The terms represent; PG, post gastric fraction leaving the stomach; IN, fraction entering the serum-dialyzable fraction; OUT, fraction remaining in the GI tract-undialyzable fraction. ND, not detected
