✦ Synopsis


Yuzu (Citrus junos Tanaka) fruit samples were obtained in November 1998 from the principal producing districts in Japan and Korea, areas which are similar with regard to latitude. Cold-pressed essential oils of the peels of the various yuzu fruits were simultaneously prepared and the chemical compositions of their volatile parts were quantitatively determined by capillary GC and GC±MS. The quantities, represented by weight percent, were examined statistically by analysis of variance followed by Duncan's multiple range test. Monoterpene hydrocarbons were found in higher concentration in the Japanese yuzu oils than in Korean ones except those from Kochi (Japanese), while the concentration of the oxygenated compounds was higher in one of the Korean samples. It was noted that there were signi®cant dierences in the concentration of limonene, b-phelladrene, linalol, (E)-b-farnesene, bicyclogermacrene, and (E)-nerolidol in the samples. Copyright
