ABSTRACT

In this study 120 compounds were found and 71 volatile compounds were identified in the essential oil of kumquat. A simultaneous distillation/extraction technique was used to obtain the essential oil from the fruit. Individual compounds were identified by means of Kovats retention indices on polar and nonpolar columns and mass spectral data. Some 13 sesquiterpenes, 8 terpenes, 11 alcohols, 1 ketone, 8 aldehydes and 13 esters were identified in kumquat oil for the fist time. Limonene was the most abundant compound comprising 93% of the whole oil.
