Abstract
Arecae semen extract relaxed aortic ring preparations of isolated rat aorta that contained endothelium from 3x10-7 g/mL, reaching a maximum of 86% at 10-5 g/mL. Its relaxation did not occur in specimens without endothelium, and was inhibited by pretreatment with 10-4 M N(G)-nitro-1-arginine methylester. One of the active components was arecoline which is a muscarinic receptor agonist. Another active component was condensed tannin contained in Arecae semen.
