Purification of the precipitate obtained from juice oil of Citrus hassaku by chromatography afforded a main compound, whose structure was determined to be 7-geranyloxycoumarin, aurapten, on the basis of chemical and spectral evidence. This compound was isolated from Citrus hassaku for the first time. The antimicrobial activity of aurapten and several synthesized related coumarins against 5 bacteria and a fungus was investigated using the agar dilution method. Auraptenal exhibited the highest activity among them, at the concentration of 25 ppm, against all the microorganisms tested in this study.
