| Abstract: | "In this study, a headspace solid-phase microextraction (HS-SPME) method, in combination with gas chromatography flame ionisation detector and gas chromatography-mass spectrometry, has been developed for use in the analysis of the volatile compounds of Teucrium flavum L. subsp. flavum, a plant whose particular fragrance is used in the preparation of flavoured wines, bitters and liqueurs, or as a substitute for hops in the flavouring of beer. The tested fibres were 100 microm poly(dimethylsiloxane) (PDMS), the 65 microm PDMS/divinylbenzene (DVB) and 50/30 microm DVB-carboxen-PDMS. The best fibre was found to be PDMS when working in the following conditions: 60 degrees C temperature, 30 min extraction time, 30 mg sample amount, 1 mm sample particle size. The HS-SPME method permitted the identification (95.8-97.8%) of 76 (dry) and 66 (fresh) different volatiles. In addition, we discovered that the presence of water in the sample can enhance the absolute quantity of alcoholic compounds such as 1-octen-3-ol and reduce the presence of esters such as methyl geranate" |
