摘要
new flavone derivative, 3′-( γ , γ -dimethylallyloxy)-5,7-dihydroxy-4′-methoxyflavone ( 1 ), was isolated from Flos Sophorae Immaturus through microbial transformation by the fungus Nigrospora sphaerica ZMT05. Its structure was elucidated by comprehensive spectroscopic analyses. This compound showed moderate in vitro antifungal activities against Colletotrichum musae and Penicillium italicum .
