Sažetak
Abstract:The research has been focusedon the phytochemical fingerprinting from different natural sources (aromatic plants, honey, or marine algae), using advanced chemical methods and hyphenated techniques. Gas chromatography with mass spectrometry (GC-MS) is appropriate hyphenated technique for the research of headspace, volatile and semi-volatile compounds present in different samplesthat could be useful for their classification, particularly since specific or non-specific chemical markers of the botanicalorigin can be found and/or specific chemical fingerprints can be determined.Different classes or natural organic compounds can be found such as terpenes (particularly monoterpenes and sesquiterpenes), norizoprenoids, benzene derivatives, others.However, before the analysis it is necessary to perform adequate preparation steps such as: ultrasonic solvent extraction (USE), headspace-solid phase microextraction (HS- SPME), solid-phase extraction (SPE), supercritical CO2extraction (SC-CO2), hydrodistillation(HD)and simultaneoushydrodistillation extraction (SDE). owever, the artefacts can be generated during the extraction steps (particularly due to the influence of heat and/or water) and different methods should be used to establish the artefacts formation.To obtain reliable chemical profiles it is often necessary to use different preparative techniques since the use of only one extraction method can neglect certain group of compounds.
