The structures of the compounds were characterized by 1H NMR, 13C NMR and HRMS spectra. Thebioassays indicated that the fungicidal activities of compounds 10b（EC50=14.82 mg/L） and 10c（EC50=18.72 mg/L）against Cercospora arachidicola Hori in vitro were much higher than that of Azoxystrobin as control（EC50=40.54mg/L） and the fungicidal activities of compounds 10u（EC50=8.66 rag/L） and 10n（EC50=9.89 rag/L） against Rhizotoniacerealis in vitro were higher than that of the same control（EC50=10.86 rag/L）. Compounds 10b, 10c, 1011 and 10kcould be considered as the leading compounds for further investigation.展开更多
