Betulinic acid (BA) exhibits many biological effects including anti-inflammatory and anti-oxidant activities. Free radicals and pro-inflammatory mediators play an important role in the pathology of inflammatory bowel disease (IBD) and associated pain. We, therefore, examined the anti-oxidant, anti-inflammatory, and anti-nociceptive potential of BA in colitis. Colitis was induced with 3% (w/v) dextran sulfate sodium (DSS) in drinking water in mice for 1to7 days. BA (3, 10 and 30 mg/kg) was given orally for 0 to 7 days. BA was also tested for its efficacy in acetic acid and mustard oil-induced visceral nociception in mice at same doses. BA significantly prevented diarrhea; bleeding and colonic pathological changes induced by DSS. Further, BA reduced the colon nitrite, malondialdehyde, myeloperoxidase, and lipid hydroperoxide levels and restored the superoxide dismutase, catalase and reduced glutathione levels …
