Relaxant effect of limonene, carveol, and perillyl alcohol on pharmacomechanical coupling. Sustained contractions induced by PHE (0.1 μM) in endothelium-intact (A) and endothelium-denuded (B) rat aortic rings. Results are shown as means ± SEM. * indicates statistical difference of limonene, carveol, and perillyl alcohol compared to the control (p < 0.05, two way ANOVA and Holm-Sidak test). # indicates statistical difference between limonene (600 μM) compared to the control (p < 0.05, one-way ANOVA and Holm-Sidak test). Each control consisted of the same concentration of vehicle as in the experimental case, but without the experimental substance.
