It was established that the relaxant effect of flavonoid pulicarin in conditions of phenylephrine and KCl- induced contraction was related to the inhibition of the influx of Ca2+ ions through the receptor-operated and potential-dependent Ca2+-channels of smooth muscle cell (SMC). The relaxant effect of pulicarin was revealed to be endothelium dependent and caused by the activation of NO/guanylate cyclase system.
