Table 4: Effect of BuOH fraction and EtOAc fraction on colonic MPO activity and TBARS levels in TNBS-induced colitis in rats.

Group Colon MPO activity (U/mg of protein) Colon TBARS levels (mol TBARS/mg of protein) Noncolitic 0.642 ± 0.061** 4.294 ± 0.707** Colitic nontreated 2.891 ± 0.740 5.737 ± 0.139 BuOH fraction 0.5 mg/Kg 0.896 ± 0.102** 4.171 ± 0.106*** EtOAc fraction 1.5 mg/Kg 2.264 ± 0.429 7.218 ± 0.776

Results are presented as mean ± SEM ANOVA followed by Dunnett’s t-test, *, **, *** significantly different from colitic nontreated.
