    Abstract:
    AIM: The aim of the present study was to examine the effects of 3,5-dicaffeoyl-4-malonylquinic acid (CA1), extract from Centella Asiatica, in rats subjected to experimental colitis. RESULTS: Colitis was induced in rats by intracolonic instillation of dinitrobenzene sulphonic acid (DNBS). CA1 was administered daily orally (0.2 or 2 mg/kg). Four days after DNBS administration, treatment with CA1 significantly reduced the appearance of diarrhoea and the loss of body weight. This was associated with a significant reduction in colonic MPO activity. CA1 also reduced NF-kappaB activation, the pro-inflammatory cytokines release, the appearance of I-NOS, nitrotyrosine, PARP and proMMP-9 and -2 activity in the colon and reduced the up-regulation of ICAM-1 and the expression of P-Selectin. CONCLUSIONS: The results of this study suggested that administration of CA1 may be beneficial for treatment of inflammatory bowel disease.
