The volatile constituents of spent hop (obtained by industrial
supercritical CO(2) extraction) were extracted using the Deryng apparatus
and determined by gas chromatography and gas chromatography–mass
spectrometry. Isooctane containing hexadecane as an internal standard was
used as an extracting solvent. beta-Myrcene (241 µg/g) was a predominant
component of the spent hop obtained by supercritical CO(2) extraction of
hop variety Marynka. Limonene (7.83 µg/g), linalool (8.08 µg/g), geraniol
(3.08 µg/g), 2-undecanone (1.36 µg/g), beta-caryophyllene (11.2 µg/g), and
alpha-humulene (19.1 µg/g) also were determined. Caryophyllene oxide was
not detected. Keywords: Deryng apparatus, Essential oils, Spent hop

cromatografía de gases–espectrometría de masas. El isooctano que contenía
hexadecano como estándar interno fue utilizado como solvente que extraía.
