Dioecious hemp (Cannabis sativa L.) is an industrial crop utilised for various purposes, including fibre, seeds, and plant extracts. The seeds and plant extracts are used for food, pharmaceuticals, or cosmetic products. This study explores the therapeutic potential of dioecious hemp by analysing the antibacterial activity of hydroalcoholic extracts from four varieties of CS: CS 1 - Armanca, CS 2 - Lovrin 110, CS 3 - Silvana, and CS 4 - Teodora. The antibacterial properties of the examined extracts were evaluated against two clinically significant ATCC bacterial strains: Staphylococcus aureus (ATCC 25923) and Escherichia coli (ATCC 25922). The main parameters assessed included bacterial growth percentage (BGP%) and bacterial inhibition percentage (BIP%), and minimum inhibitory concentration (MIC). These were utilised to evaluate the effectiveness of the extracts. The findings indicated a positive correlation between the concentration of CS extract and its antibacterial activity. Specifically, higher extract concentrations resulted in stronger inhibitory effects on bacterial growth. However, further research is crucial to fully understand the potential of hemp hydroalcoholic extracts as components in antibacterial pharmaceutical products.
