Abstract: Isolation of volatile and fixed oils from dried berries of Laurus nobilis L. from
Tunisia have been obtained by supercritical fractioned extraction with carbon dioxide.
Extraction experiments were carried out at a temperature of 00 °C and pressures of 00 and
000 bar. The extraction step performed at 00 bar produced a volatile fraction mainly
composed of (E)-β-ocimene (00.0%), 0,0-cineole (0.0%), α-pinene (0.0%), β-longipinene
(0.0%), linalool acetate (0.0%), cadinene (0.0%), β-pinene (0.0%), α-terpinyl acetate
(0.0%) and α-bulnesene (0.0%). The oil yield in this step of the process was 0.0 % by
weight charged. The last extraction step at 000 bar produced an odorless liquid fraction, in
which a very small percentage of fragrance compounds was found, whereas
triacylglycerols were dominant. The yield of this step was 00.0 % by weight. The most
represented fatty acids of the whole berry fixed oil were 00:0 (00.0%), 00:0 n-0 (00.0%),
00:0 n-0 (00.0%), and 00:0 (00,0%), with the 00:0 n-0 and 00:0 n-0 unsaturated fatty acids
in particular averaging 000 μg/mg of oil.
