Antimicrobial activity of three Eryngium L. species (Apiaceae)
Abstract
The antimicrobial activity of ethanolic extracts from leaves and roots of three Eryngium L.
genera (E. planum, E. campestre, E. maritimum) native to Poland was tested by the method
of series dilutions against different Gram-positive bacteria (two strains) and fungi (five species).
The extracts were analyzed by TLC method to confirm phenolic acids, triterpenoid
saponins, flavonoids and acetylenes presence. The antimicrobial activity of extracts compared
with the reference substance were expressed by Minimal Inhibitory Concentration
(MI C). The results have shown that the ethanolic extracts inhibit the growth of Staphylococcus
aureus and all tested fungi.
