Congress Abstract

Essential oils from Acorus tatarinowii Schott. and Acorus calamus Linn. were obtained by hydrodistillation and bioassay guided fractionation to isolate, identify, and characterize compounds with antifungal activity. Eleven compounds from two Acorus species were isolated using column chromatography, preparative TLC, and preparative HPLC. Structure elucidation was performed on all isolated compounds using a combination of gas chromatography-mass spectrometry-electron ionization, and one- and two- dimensional NMR experiments. Five isolated compounds from two Acorus species had antifungal activity. Compounds 1-7 might yield novel biopesticidal mosquito control agents.
