AA as a well-known antioxidant can protect tea
polyphenols from oxidation. We also found that the
synergistic effects of TF3+AA and EGCG+AA on
SPC-A-1 cells were through cell cycle arrest, but the
EGCG or TF3 alone can lead to more apoptosis. In
synergistic cultures, the relative number of apoptotic
cells did not increase; a maximum of 2.1% of apoptotic
cells were observed. TF3 can increase the cell
cycle at the G0/G1 phase. When AA is added, it can
produce a large amount of H2O2 by reducing the
concentration of peroxidase (Zheng et al., 2002). TF3
shows the most potent hydroxyl radicals-scavenging
ability (Yang et al., 2008).
