Relaxant effect of essential oil and hydro-alcoholic extract of Pycnocycla spinosa Decne. exBoiss. on ileum contractions.

Pycnocycla spinosa is an essential oil from a wild plant growing in central Iran. However, so far its pharmacological effects have not been studied. The aim of this study was to look for relaxant effects of the essential oil and hydro-alcoholic extract of P. spinosa on rat isolated ileum contractions induced by KCl and acetylcholine (ACh). P. spinosa essential oil (PSEO) and the hydro-alcoholic extract inhibited the response to 80 mM KCl in a concentration-dependent manner and attenuated the maximum attainable response of ACh concentration-response curve. Furthermore, in caster oil induced diarrhoea, the hydro-alcoholic extract had a dose-dependent anti-diarrhoeal effect. This study showed that P. spinosa essential oil and its hydro-alcoholic extract act as a relaxant of rat isolated ileum. As the inhibition of contractile over-activity of the ileum is the basis for the treatment of gastro-intestinal disorders such as diarrhoea, P. spinosa may have clinical bene fi ts for treatment of this condition.[1]
