From: Effects of tea, catechins and catechin derivatives on Omicron subvariants of SARS-CoV-2
Analysis of inactivation effects of tea and green tea catechins on SARS-CoV-2 Omicron variants. Viruses were treated with the indicated tea (a) or each catechin at the same concentration in bottled green tea beverage (Supplementary Table 1) (b) for 10 s. After dilution, the virus was infected to VeroE6/TMPRSS2 cells to determine TCID50 values as described in the Materials and Methods. Virus titer of each sample (means ± S.D.) is shown (n = 4). ****p < 0.0001, ***p < 0.001, **p < 0.01, and *p < 0.05 vs. Control (distilled water) (Tukey’s multiple comparisons test).
