Increasing demands for both crude medicinal plants and natural products based on herbs, the risk of excessive collection from the wild, and more protected areas have led to a growth in small- and large- scale cultivation. It is the only way to supply the contracted volume and high quality of special crop raw material. One of the places in Slovakia where intensive research and development with medicinal plants is carried out is the University of Presov in Presov, Eastern Slovakia. The present agro-technology research & development of medicinal and aromatic plants are concentrated to all aspects of their biodiversity, breeding and cultivation. The Presov university garden contains a number of different herbs: German chamomile (Matricaria recutita L.), lemon balm (Melissa officinalis L.), marigold (Calendula officinalis L.), agrimony (Agrimonia eupatoria L.), sage (Salvia officinalis L.), hyssop (Hyssopus officinalis L.), common mallow (Malva silvestris L.), grown for home use and local sales. The objective of this study was the qualitative and quantitative analysis of the essential oil composition in peppermint (Mentha ×piperita L.), our variety ‘KRISTINKA’, grown on the university field. We studied the essential oil composition over last five consecutive years and determined the stability of the chemical composition of the main secondary metabolites in this cultivar.
