Effect of Cymbopogon citratus and Citral on Vascular Smooth Muscle of the Isolated Thoracic Rat Aorta

Figure 5

Dose-response curves for calcium in the presence and absence of (a) 6.24 mM citral and (b) 30 mg/mL of the extract from leaves (LE) and (c) roots (RE) of C. citratus on the PE-induced contraction in Ca²⁺-free Krebs solution in endothelial intact (E+) and endothelial denuded (E−) aortic rings of SHR rats. All the data were significant at **𝑃<0.001 compared to the PE-induced contraction in the corresponding E+ and E− aortic rings. Values were shown as means ± S.E.M. with 𝑛=6 rats.
