Zanthoxylum bungeanum essential oil composition analysis and its antifungal activity on four kinds of plant pathogenic fungi
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.
