Objective To explore the anti-inflammatory effects of magnoliae fargesii volatile oil.Methods Human umbilical vein endothelial cells (HUVECs) were stimulated by TNF-α to express the adhesion molecules. Then the anti-adhesion effects of magnoliae fargesii volatile oil between HUVECs and human peripheral neutrophils were observed. The ischemia-reperfusion animal models were established by 60min renal ischemia followed by 1, 3, 6 and 24h reperfusion. Rats were randomly divided into the following groups: the sham-operation controls, ischemic group only treated with normal saline, and treated group infused magnoliae fargesii volatile oil before reperfusion. Then the renal injury of rats was detected. Results High rate of cell adhesion between HUVECs and neutrophils was observed. Magnoliae fargesii volatile oil could inhibit the adhesion process at the concentration of 0.5μL/mL (191.6±8.6), 1.0μL/mL (158.2±9.0) and 2.0μL/mL (155.2±9.7) (P<0.05). The anti-adhesion effects were strengthened with the increase of volatile oil concentration. Blood urea nitrogen and creatinine levels of the animal models were significantly increased after 24h reperfusion while the increase was remarkably attenuated by the treatment with magnoliae fargesii volatile oil. The renal injury was severe after 1h reperfusion, which was significantly attenuated by the treatment of magnoliae fargesii volatile oil. Conclusion Magnoliae fargesii volatile oil has anti-inflammatory effects.

Then the anti-adhesion effects of magnoliae fargesii volatile oil between HUVECs and human peripheral neutrophils were observed. The ischemia-reperfusion animal models were established by 60 min renal ischemia followed by 1,3, 6 and 24 h reperfusion. Rats were randomly divided into the following groups ： the sham-operation controls, ischemic group only treated with normal saline, and treated group infused magnoliae fargesii volatile oil before reperfusion. Then the renal injury of rats was detected. Results High rate of cell adhesion between HUVECs and neutrophils was observed. Magnoliae fargesii volatile oil could inhibit the adhesion process at the concentration of 0. 5 μL/mL （191.6 ±8. 6）, 1. 0 μL/mL （158. 2 ±9. 0） and2. 0μL/mL （155.2 ±9. 7） （ P 〈0. 05）. The anti-adhesion effects were strengthened with the increase of volatile oil concentration.
