Abstract
Abstract A new antifungal substance against rice blast fungus ( Pyricularia oryzae ), 5-(8′Z-heptadecenyl)resorcinol, was isolated from etiolated rice seedlings together with a mixture of its homologues with C 13 , C 15 , and C 17 saturated alkyl chains. Its structure was determined by 1 NMR, 13 C-NMR, and MS spectra. Its ED 50 was ca 40μg/ml. These 5-alkylresorcinols were newly produced after germination and the concentration reached 50 μg g −1 fresh weight on day 6.
