Chemical composition and antifungal activity of essential oils of Eupatorium catarium and Eupatorium odoratum from China

Abstract

Essential oils of two compositae species, including Eupatorium catarium and Eupatorium odoratum, harvested in Hainan province, extracted by hydrodistillation, were analyzed by GC and GC/MS. The antifungal activity of the oils against 8 phytopathogenic fungi (Fusarium graminearum, Botrytis cinerea, Exerohilum turcicum, Mucor, Sclerotinia sclerotiorum, Rhizoctonia solani AG1-IA, Rhizoctonia solani Kühn, Fusarium graminearum Schwabe.) was tested by determining minimum inhibitory concentrations (MIC) using the microdilution method. The two oils exhibited potent antifungal activities.
