Zanthoxylum bungeanum essential oil was extracted using the Soxhlet method.The effects of Zanthoxylum bungeanum es-sential oil on Fusarium oxysporum,Fusarium graminearum,Colletotrichum gloeosporioides and Alternaria solani were evaluated by the mycelial growth rate method.The composition of Zanthoxylum bungeanum essential oil was analyzed using gas chromatography-mass spectrometry(GC-MS).The results showed that Zanthoxylum bungeanum essential oil exhibited antifungal activity Fusarium grami-niearum,Fusarium oxysporum,Colletotrichum gloeosporioides and Alternaria solani,with median effect concentration(EC50)of 1.552,2.243,6.064,7.078 mg/mL,respectively.GC-MS analysis revealed that the principal constituents of Zanthoxylum zanthoxy-lum essential oil were terpenoids including linalyl acetate,linalool,D-limonene and eucalyptol.
