Three new griseofulvin derivatives from .

Three new griseofulvin derivatives, griseofulvinoside A-C (-), were isolated from the ethyl acetate extract of the solid fermentation product of . Their structures were elucidated based on extensive spectroscopic data analysis of MS, 1D and 2D NMR. The antifungal activities of new compounds were evaluated against four phytopathogenic fungi , and all test compounds demonstrated inhibitory effects. Among them, compound exhibited the most potent activities against the four selected phytopathogenic fungi with inhibitory rates ranging from 40.2 to 75.8% at 0.2 mg/mL.
