Abstract
The identification and introduction of medicinal plants hold significant importance in modern life. The genus Pycnocycla, belonging to the Apiaceae family, includes eight endemic species in Iran. P. spinosa has attracted attention due to its medicinal properties. This study aims to investigate the effect of three habitats (the Damghan, Semnan, and Kerman city) on the antimicrobial properties of extracts obtained from Pycnocycla spinosa using different solvents. To examine the antimicrobial properties, methanolic, ethyl acetate, and hexane extracts at a concentration of 2 mg/ml were tested against two pathogenic Gram-negative bacteria, Yersinia enterocolitica and Salmonella enterica, using the agar disk diffusion method. The results indicated that the extracts had varying effects on the bacteria. Additionally, the different geographical regions of Iran, due to their distinct climatic conditions, exhibited varying effects on the bacteria. Extracts from Kerman, especially those using methanol and ethyl acetate as solvents, showed the highest antimicrobial activity against Salmonella enterica. Therefore, the type of solvent and habitat can significantly influence the antimicrobial properties of plants.
