ABSTRACT
Objective To investigate the different effects of 2 species of Fructus aurantii immaturus on cardiovascular and respiratory system.Methods The extract of 2 species of Fructus aurantii immaturus were administered to anesthetized rats by duodenum and the dosages were 4.2,2.1 g crude drug/kg respectively.After administration,a continuous observation of blood pressure,respiration and ECG effects for 4 hours were performed.Results Compared with the control group,both of Citrus aurantium and Citrus sinesis exerted a transient increase to respiration rate after 20 min administration.No significant impact was observed during the experiment period on the ECG.The influence of Citrus aurantium on blood pressure was more significant.Compared with the control group,the effects of SBP,DBP and MBP reduced was observed in high-dose group of Citrus aurantium after 40,60,80 min administration,and so in low-dose group of Citrus aurantium after 60 min.The impact duration was up to 2 hours or more.However,the antihypertensive effect of Citrus sinesis was not obvious.And the blood pressure lowering effect of Citrus aurantium was superior to Citrus sinesis.Conclusion The 2 species of Fructus aurantii immaturus exert a transient excitatory effect on respiratory system.And the direct effect of them on heart is not obvious.The blood pressure lowering effect of Citrus aurantium is superior to Citrus sinesis.The attention should be given in the clinical usage of Fructus aurantii immaturus.
