The promotion of apoptosis of HT-29 cells by tea extracts with various storage years. HT-29 cells were treated with 0.2 mg/mL extract of different tea samples 03Y, 07Y, 11Y, 15Y and 19Y for 24 (A,B) and 48 h (C,D), respectively. Total 0.2 mg/mL cisplatin was used as a positive control (Pos group). The proportion of apoptotic cells in each group was examined and counted using flow cytometry. One-way ANOVA analysis was performed between the treatments of multiple tea samples. The different lowercase letters (a, b, c, d) in the same group show the significant differences at p < 0.05 level.
