摘　　要：老年性肠功能减退和肠癌多发已成为常见病,近年注意到适量食用猕猴桃可增进胃肠运动.本文通过对小鼠离体肠肌运动的研究,解析猕猴桃成分的功效.经解析,猕猴桃含有丰富的小分子有机酸和游离糖,以及适量膳食纤维(Dietary fiber,DF).研究发现,2.0%葡萄糖-1.0%酒石酸混合溶液、2.5%DF和2%可溶性膳食纤维果胶(Soluble dietary fiber-pectin,SDF-P)均可有效增进小鼠肠肌运动,使肠肌收缩频率极显箸提高(p<0.01).猕猴桃增进肠运动的主要功效成分是小分子糖酸、DF和SDF-P等,它们共同降低肠道内酸度和增加晶体渗透压,对肠壁产生适宜的化学和机械性刺激,促进了肠蠕动.Intestinal dysfunction and cancer have been increased in elders recently. It is very interesting that eating one or two kiwi （ actinidia ） a day can improve the gastrointestinal movement effectively. Actinidia functional composition is studied by HPLC and intestinal segment movement in vitro. There are richer small molecular organic acids,free sugars and dietary fiber （ DF ） in actinidia. The contraction frequency （ CF ） of intestinal muscle can be raised significantly （p〈0. 01）,because of adding mixed solution of 0. 2% glucose -0. 1% tartaric acid,2. 5% DF or 2% Soluble dietary fiber-pectin（ SDF-P） . The mainly functional components in actinidia are small molecular organic acids,free sugars,and DF and SDF-P. They increase intestinal movement via suitable stimulus such as lower pH value and higher crystal osmotic in intestine.
