Hemp (Cannabis sativa L.) is one of the oldest cultivated plants that has been used mostly as a source of fibre, oil, food and medicine. It contains many secondary metabolites. The most studied are cannabinoids, especially THC (delta-9-tetrahydrocannabinol) which is psychoactive and CBD (cannabidiol) which is non-psychoactive [1]. Hemp varieties have generally low content of cannabinoids in comparison with medical marijuana, but in hemp varieties the ratio between CBD and THC could be still 10:1 [2]. The highest content of cannabinoids is in inflorescences, especially in flower trichomes, while seeds do not contain any cannabinoids [3]. The aim of our study was to compare content of cannabinoids CBD-A and THC-A, precursors of CBD and THC in 15 hemp varieties grown in years 2017 and 2018 on two different locations in Slovenia, Žalec and Gornja Radgona. The highest content of CBD-A was achieved in variety ‘Antal’ (2017) and in variety ‘Helena’ (2018) and the lowest content in variety ‘Santhica’ (2017 and 2018). The content of THC-A was the highest in variety ‘Tiborszallasi’ (2017) and in variety ‘Antal’ (2018), while the lowest content was determined in variety ‘Santhica’ (2017 and 2018). Based on this study, farmers will be able to grow hemp varieties with higher content of CBD-A which could be used for pharmaceutical purposes.
