Background\Aim: Many Eryngium species have been used as remedies in traditional medicine. Genus Eryngium is abundant source of many medicinal plants. Eryngium amethystinum is a plant which has been traditionally used throughout Balkan peninsula and Southern Italy.
Methods: Extraction with polar and non-polar solvents was performed on aerial parts and roots of Eryingium amethystinum. Antioxidative activity of aerial plants has been investigated by DPPH test. Modest antioxidative activity of aerial parts of Eryngium amethystinum has been shown. The main compounds of Eryngium amethystinum water extract were germacrene D, spathulenol and campestrol. The linkage between polarity of solvent for extraction and antimicrobial activity has been tested.
Results: Extracts of the aerial parts presented as minimum inhibitory concentration ( MIC), expressed the activity in the range 0.009-18.00 mg/ mL, with the highest activity exhibited by ethyl acetate extract. All the extracts expressed the highest potential against Staphylococcus aureus and Gram – negative bacteria of Klebsiella pneumoniae.
Conclusion: The obtained results suggest that Eryngium amethystinum can be considerable source of new antibacterial molecules and new antioxidant agents as well.
