The pharmacological activity of the aerial (EKA) and root (EKR) parts of the endemic plant, Eryngium kotschyi Boiss., on rat isolated ileum and detrusor muscle was investigated. Plant extracts alone and with the presence of agonist (acethylcholine) and antagonist (atropin, verapamile, oxybutinine-detrusor muscle, and papaverine-ileum) drugs, along with Ca2+ applications on calcium-free medium, were applied. Plant extracts induced contraction in ileum and detrusor muscle where the contractions were concentration dependant for EKA and EKR single dose applications in detrusor muscle and concentration-free contractions were observed in cumulative applications for both tissues. Aerial and root parts of Eryngium extracts induced contractions in dose, tissue and protocol dependent manner where the contractions were affected by the tested antagonists, which could be attributed to non-specific pathways including calcium ions and calcium channel stimulations.
