| Abstract:
Besides analytic evaluation applied to specify the quality of herbs and volatile components of their essential oils, the modelling of human sensory evaluation with ‘electronic nose’. During one growth season, the herb of three Origanum vulgare subsp. hirtum lines and Origanum vulgare was examined by GC and ‘electronic nose’. The subsp. hirtum clones contained 3-4% essential oil, Origanum vulgare had only 0.2% in full flowering. Regarding the essential oil components, the subsp. hirtum lines and Origanum vulgare contained the same quantity of carvacrol in the whole growth season, while one selected subsp. hirtum line showed significantly more p-cymene and  -terpinene from the beginning of green bud phase.
The complex of aromatics was different for all selected lines according to the distinction of the sensor signals of electronic nose.
