Resumen
Volatile compounds of basil (Ocimum basilicum L.) were extracted with solid phase microextraction (SPME) and analyzed with gas chromatography-mass spectrometry (GC-MS). Two SPME fiber coatings, Polydimethylsiloxane/Divinylbenzene (PDMS/DVB, 65 ?m) and Carbowax/ Divinylbenzene (CW/DVB, 65 ?m) were evaluated in order to compare the extraction of components. Among the 25 volatile compounds detected were phenylpropanoids, monoterpenes, sesquiterpenes, esters, and aldehydes. There were significant (P < 0,05) differences between the two analyzed fibers: with CW/DVB fiber is apparently superior with respect to the number of components isolated as well as the total concentration of compounds. Quantitatively, the most important component was methyl cinnamate, followed by linalool.
