Essential oil of Perilla frutescens BRITTON var. crispa DECCAISNE f. discolor MAKINO contains two principle constituents. One is perilla ketone and the other is a new β-furyl ketone. The latter was separated by rectification and fractional gas chromatography. Through infrared and nuclear magnetic resonance spectra, and ozone oxidation, this substance was found to be isoegomaketone 1-(3-furyl)-4-methyl-2-penten-1-one.
