Colpomenia sinuosa (Mertens ex Roth) Derbès & Solier, 1851 is thallus
bladder-like, smooth, slick, hollow, crisp, spherical to sac-like, irregularly
expanded or somewhat lobed, to 30 cm diameter, 10 cm high. This golden-
brown alga belongs to Scytosiphonaceae family. The sample was collected in
the Adriatic Sea close to Island Vis (43° 03' 47'' N, 16° 11' 15'' E). Volatiles of
fresh C. sinuosa were extracted by headspace solid-phasemicroextraction (HS-
SPME) and analysed by gas chromatography and mass spectrometry (GC-MS).
In this investigation of alga headspace volatile organic compounds (VOCs),
two fibers were used: namely polydimethylsiloxane/ divinylbenzene (PDMS/
DVB) and divinylbenzene/carboxene/polydimethylsiloxane (DVB/CAR/PDMS).
The major C. sinuosa volatile compounds (PDMS/DVB; DVB/CAR/PDMS)
were: dictyopterene D (6-[(Z)-1-butenyl]-1,4-cycloheptadiene) (26.7%; 10.9%),
Dictyopterene C' (6-Butyl-1,4-cycloheptadiene) (11.4%, 2.7%), dimethyl sulfid
(8.4%; 18.3%), tridecanal (5.1%; 6.3%), pentadecanal (5.0%; 2.4%), 1-pentene-
3-on (2.2%; 3.4%), octan-1-ol (1.2%; 3.1%), -Ionone (3,8%; 5,8%) and S-methyl
thioacetate (-; 3.3 %). Application of headspace solid-phase microextraction
enables identification of low-molecular organic compounds. Among those
volatiles, biologically active compound can be found such as allelochemicals,
defensive compounds, sex attractants or pheromones.
