Abstract: This study aims to determining the preventive effects of fermented Chimonobambusa quadrangu‐laris shoot (FCQS) on Montmorillonite powder induced constipation through the animal experiments .The influence of FCQS on constipation mice has beenassessed by buildingof constipation animal model .The re‐sults show that the body weight changes of FCQS fed mice were close to the normal mice ,and the body weights were higher than the control mice .The time for first black stool defecation of FCQS fed group (104min) is lower than control group (185min) and unfermented Chimonobambusa quadrangularis shoot (CQS ) fed group (122min ) , but higher than the normal group (68min ) and bisacodyl treated group (90min) .The intestinal transit of FCQS fed group (68 .7% ) is higher than the control group (38 .3% ) and CQS fed group (50 .4% ) ,and is lower than normal group (98 .3% ) and bisacodyl treated group (79 .3% ) . The serum levels of MTL (motilin) ,ET‐1 (endothelin‐1) ,VIP (vasoactive intestinal peptide) and AchE (acetylcholinesterase)arealso higher than control group and CQS fed group ,but lower than normal group and bisacodyl treated group .The fiber quality of FCQS is better than that of CQS through microscopic ex‐amination .FCQS is an healthy food which exhibits goodinhibitory effect on constipation .
