It is well known, that environmental and biological data are usually characterized by high variability, because of a variety of natural and anthropogenic influences. The best approach to avoid misinterpretation of environmental and biological objects is the application of chemometric methods for classification and modeling (Kowalkowski, et al. 2006). The multidimensional data analysis methods are very popular in such studies dealing with measurements and monitoring (Bro et al. 2002; Munck et al. 1998).
Current work is focused on the separation and determination of volatile organic compounds in essential oils from different forms of wild hops cones and a few varieties of domestic hops cones cultivated at the same collection by means of gas chromatography coupled with mass spectrometry (GC-MS). Volatile compounds were isolated using extraction methods such as steam distillation, SPME, SFE, and ASE. The qualitative characterisation of analysed essential oil samples by GC-MS was performed. Chemometric methods were used for the clasification of obtained data.
