甘草、白芍水提合剂(0.21g)对在体兔肠管平滑肌运动有明显的抑制作用,两者合用较单用效果好,降频率作用较降幅度作用强。给药后20～25min降低兔肠管收缩频率分别为正常对照组的64.71％和70.59％,二者比较有显著性差异(P<0.05;P<0.01).与阳性对照组阿托品(0.25mg)比较,给药后20min降低肠收缩率 Glycyrrhizae radix and Radix Angelicae Dahuricae (0.21g) had significant inhibitory effects on the smooth muscle movement of rabbit intestine. The combination of them had better effect than single use, and the frequency-decrease effect was stronger than the decrease amplitude. The rabbit intestine contraction frequency was reduced by 64.71% and 70.59% in the normal control group at 20-25 minutes after administration, which was significantly different (P<0.05; P<0.01). Compared with the positive control group, atropine (0.25 mg). , reduce the intestinal contraction rate 20 minutes after administration
