cqvip:[Objectives]To explore the difference of purgative effect of Mongolian medicine Euphorbia pekinensis and Pharbitidis Semen(black)by animal experiment,taking Euphorbia pekinensis and Pharbitidis Semen(black)as the research object.[Methods]Sixty Kunming mice were randomly divided into blank group(n=20),Euphorbia pekinensis group(n=20)and Pharbitidis Semen(black)group(n=20).After fasted but provided with free acess to drinking water for 3 d,the mice were intragastrically administered with drinking water,Euphorbia pekinensis test solution and Pharbitidis Semen(black)test solution,respectively.The mice were then placed separately in a mouse cage covered with filter paper for purgation test and intestinal propulsion test.[Results]The time of the first purgation in the Euphorbia pekinensis group and the Pharbitidis Semen(black)group was longer than that in the blank group(P<0.05).The total times of purgation and defecation within 5 h in the Euphorbia pekinensis group and the Pharbitidis Semen(black)group were higher than those in the blank group(P<0.05);the purgation index and intestinal propulsion rate in the Euphorbia pekinensis group and the Pharbitidis Semen(black)group were higher than those in the blank group(P<0.05).[Conclusions]The Mongolian medicine Euphorbia pekinensis was similar to Pharbitidis Semen(black)in purgation test and intestinal propulsion test,and could play a substitute role.
