The broth of Cordyceps cicadae fermented in oscillating manner was extracted with ethyl acetate, and antifungal activity of the extract was tested by Oxford cup method. Active substances from the ethyl acetate extract were purified by high performance liquid chromatography. The chemical structure of the active compound was identified by physio-chemical properties and spectral data. Our experiment showed that the ethyl acetate extract presented a significant inhibiting effect against Canidia albicans, sugges...
