Abstract

Aqueous extracts of Tapinanthus dodoneifolius DC Danser. (Loranthaceae) (AETD) were investigated for cardiovascular activities on isolated rat aorta and heart. AETD did not affect heart rate but significantly enhanced heart contraction force and relaxation capacity. AETD (0.001-1mg/ml) elicited a dose-dependent relaxation on arteries which was previously contracted with phenylephrine [10-6M] (rat aorta). AETD induces relaxation in endothelium dependent manner. When Indomethacin failed to inhibit AETD vasodilatory activity, in the presence of L-NAME, the vasodilatory activity of AETD was completely abolished. These results suggest a cardiotropic activity without any tachycardia as a side effect for AETD. However, AETD elicited vasodilatory activity which involved NO from endothelium.
