Objective: To study the effects of extractives from Pericarpium citri reticulatae(PCR) and Pogostemon cablin(Blanco)Benth(PCB)on limb Ischem ia/Reperfusion(LIR)model rat’s gastro- intestinal motility. Methods: Adopt LIR model

observe the effects of PCR water extractives

Hesperidin

PCB water extractives

PCB water extractives plus volatile oil and Patchouli alcohol on LIR model rats’ gastric emptying function and small intestinal propulsive function. Results: Contrast to the normal control group

The LIR model rats’ gastric emptying function and small intestinal propulsive function degenerated significantly(P<0.01). PCR water extractives，Hesperidin， PCB water extractives and PCB water extractives plus volatile oil could significantly mprove the LIR model rats’ gastric emptying function and small intestinal propulsive function(P<0.01)

but Patchouli alcohol had no effect.There was significant difference between PCR water extractives group and Hesperidin group

between PCB water extractives group and PCB water extractives plus volatile oil group(P<0.01). Conclusion: In the aspect of improving the LIR model rats’ gastric emptying function and small intestinal propulsive function

PCR water extractives had better effect than Hesperidin

and PCB water extractives plus volatile oil had better effect than PCB water extractives

but Patchouli alcohol had no effect.
