Plant proanthocyanidins, including procyanidins, display various biological activities. Here we report an inhibition of human colon cancer Caco-2 cell growth by the extract from Japanese quince fruit and the procyanidin-rich fractions of the extract. We observed that the amount of apoptotic Caco-2 cells increased by 52.1% vs. control after 72-h incubation with 50 μg extract/mL, as assessed by flow cytometry and image cytometry. Under the same experimental conditions the corresponding values for human colon cancer HT-29 cells and for rat normal intestinal IEC-6 cells were 5.0% and 8.1%, respectively. The extract fractions enriched with higher oligomers exhibited the highest proapoptotic activity. In conclusion, the Japanese quince procyanidins exhibited proapoptotic activity in Caco-2 cells within a submilimolar concentration range.
