Assessment of stool sample capacity to bioconvert TU‐100 and its components. Solutions of TU‐100 (A) or ginseng extract (B) were added to the stool prepared from the mice treated for 28 days with TU‐100 diet (closed column) and control diet without TU‐100 (open column). After 24 h incubation at 37°C, ingredients and metabolites were analyzed by LC‐MS/MS as described in Materials and Methods section. The values before incubation were subtracted from those after incubation and expressed as means ± SD. *P < 0.05, **P < 0.01 (n = 6).
