摘要: 目的 探讨白萝卜提取物(Er)对胃肠运动的影响及其可能的作用机制。方法 灌胃给药后,测定小鼠胃内容物的残留率、小肠中阿拉伯胶活性炭粉混合物的推进距离;制作豚鼠回肠离体肠段标本,测定给药前后肠段平滑肌收缩强度和频率的变化情况。结果 白萝卜粗提物(Ecr)、石油醚(Ept)、氯仿(Ecl)和水提物(Eaq)均可剂量依赖性地使离体豚鼠回肠平滑肌收缩,该作用可完全被吡拉明所阻断,且粗提物作用最强;白萝卜粗提物在30~100mg·kg-1时可使胃残留率明显减少,小肠推进百分比明显增加。结论 白萝卜提取物可促进胃肠运动,该作用的发挥可能是通过激动组胺H1受体实现的。

Abstract: AIM: To explore the effects of the extract of Raphanus sativus roots (Er)on gastrointestinal stimulatory activity and its possible mechanism.METHODS: After Er were administrated orally,the remaining rate of substance in stomach,the distance of charcoal meal in intestines was measured.The samples of isolated ileum segment from guinea pigs were prepared,then the contraction intensity and frequency of the smooth muscle were measured pre-and post treatment of Er.RESULTS: The crude extract(Ecr),the petroleum spirit(Ept),chloroform(Ecl)and aqueous(Eaq)fractions of Raphanus sativus roots all showed dose-dependent spasmogenicity in guineapig ileum,and could abolished by pyrilamin,the crude extract being more potent.The Er could significantly improve gastric emptying,and it also could enhance the transit of charcoal meal in mice at 30-100 mg·kg-1.CONCLUSION: The extract of Raphanus sativus roots demonstrated spasmogenic effect on gastrointestinal tract,and this effect may through activating histaminergic (H1)receptor.

Key words: Raphanus sativus roots, histamin, intestinal propulsion, gastric emptying, smooth muscle of ileum
