Objective:To study the effects of alkaloids from Phyllanthus urinaria on gastrointestinal propulsion in mice.Methods:The alkaloids in the Phyllanthus urinaria were extracted by rotary evaporator. The healthy 50 mice were randomly divided into high-dose group,middle-dose group,low-dose group,blank control group and atropine group. The effect of alkaloids from Phyllanthus urinaria on intestinal propulsion in mice was observed by the index of ink advection of the markers in the gastrointestinal tract. Result:According to the experimental data,the high dose of the advancing rate was the lowest,fol...
