Characterization of the intestinal permeability features of TSG in Caco-2 cell monolayer. a Bidirectional transport studies of TSG at different drug concentrations (10, 30 and 60 μg·mL− 1, respectively). p < 0.05 (*), p < 0.01 (**), comparison with the group at 10 μg·mL− 1 TSG. b The apparent permeability (Papp, cm/s) values of AP-BL at 1, 2, 3 and 4 h for TSG. c The apparent permeability (Papp, cm/s) values of BL-AP at 1, 2, 3 and 4 h for TSG. d The Papp of TSG at different pH values (7.4, 6.4 and 5.4, respectively). p < 0.05 (*), p < 0.01 (**), comparison with the pH 7.4 group. All results are expressed as mean ± SD (n = 3)
