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

GroupColon MPO activity
(U/mg of protein)
Colon TBARS levels
( mol TBARS/mg of protein)

Noncolitic 0.642 ± 0.061**4.294 ± 0.707**
Colitic nontreated2.891 ± 0.7405.737 ± 0.139
BuOH fraction 0.5 mg/Kg0.896 ± 0.102**4.171 ± 0.106***
EtOAc fraction 1.5 mg/Kg2.264 ± 0.4297.218 ± 0.776

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