| Control | 141.38 ± 2.54 | 84.63 ± 3.48 | 59.86 ± 1.37 |

1. Data are expressed as the mean ± SD values (n = 8). Statistical analysis was performed using one-way ANOVA with Newman-Keuls post-hoc test. #p < 0.05 vs. control group. p < 0.05 vs. loperamide group. Positive control: sodium picosulfate 0.52 mg/kg BW; NTU 101 (0.5, 1, and 5×): 1.3, 2.6, and 13 mg/kg BW, respectivel.
2. Abbreviation meaning of each group is shown in Table 1.
3. Intestinal charcoal transit ratio (%) = (transited distance of charcoal meal/total small intestine length) × 100%.
