ABSTRACT
<p><b>OBJECTIVE</b>To investigate the mechanism of iridoid from Valeriana jatamansi treating irritable bowel syndrome.</p><p><b>METHOD</b>Sixty male SD rats were equally divided into 6 groups (2 controls, 1 model and 3 treatment doses) with 10 rats per group. The test groups were administered with iridoid (24.92, 12.46, 6. 23 mg x kg(-1)) while the control groups were administered with fluoxetine (2.5 mg x kg(-1), positive control) or distilled water (negative control). The model was established by chronic stress and independent feeding. The influence of iridoid from V. jatamansi on 5-HT and 5-HIAA in colon, serum and hypothalamic were observed in all groups.</p><p><b>RESULT</b>In the model group, the content of 5-HT in colon and serum increased significantly, but the content of 5-HT in hypothalamic decreased significantly. The content of 5-HIAA and the value of 5-HT/5-HIAA had no significant change. In three iridoid-treated groups, the content of 5-HT in colon and serum decreased, but the content of 5-HT in hypothalamic increased. The content of 5-HIAA had no significant change. The value of 5-HT/5-HIAA in colon and serum reduced.</p><p><b>CONCLUSION</b>The mechanism of iridoid from V. jatamansi treating irritable bowel syndrome may be related to the regulation effect to the levels of 5-HT from Gastrointestinal to central nervous system.</p>
