当归油(含藁本内酯ligustilide>70%),用1%吐温-80助溶,无论对正常未孕离体子宫还是对经缩宫素处理的离体子宫,都可剂量依赖性(浴槽终浓度为1mg/100mL～32mg/100mL)地抑制子宫平滑肌的收缩功能,其性质与妇痛宁滴丸相似,但作用稍强,表明其有抗子宫平滑肌痉挛作用

The oil of Angelica sinensis (Oliv.) Diels (contains ligustilide 70%), could markedly inhibit the contractile function of isolated uterine smooth muscle of mice in a concentration dependent manner (the utlimate bath concentration is 1 mg/100 mL～32 mg/100 mL) whether the test sample was isolated from normal or oxytocin treated mice. It proved that angelica oil had significant anticonvulsive effect in uterine smooth muscle of mice.
