Vasorelaxant Effect of <i>Prunus mume</i> (Siebold) Siebold &amp; Zucc. Branch through the Endothelium-Dependent Pathway

Korean plum (<i>Prunus mume</i> (Siebold) Siebold &amp; Zucc.) has long been used as a health food or herbal medicine in Asia. Previous studies have shown that several plants of the genus <i>Prunus</i> have vasodilatory and antihypertensive effects; we hypothesized that &...
