    • The present invention is an isolated compound and method of inducing endothelium-dependent relaxation in blood vessels including the step of introducing isolated procyanidins having a preponderance of (−)-epicatechins to a patient wherein the procyanidins are preferably galloylated. To achieve both bioavailability and potency, it is also preferred that the number of epicatechins monomers forming each procyanidin is between two and five. More specifically, isolated epicatechin-(4-8)-epicatechin-(4-8)-epicatechin-gallate (C1-gallate) is administered to the patient.
    • 本发明是分离的化合物和诱导血管内皮依赖性松弛的方法,包括将具有优势( - ) - 表儿茶素的分离的原花青素引入到其中原花青素优选被加成半乳糖化的步骤的步骤。 为了实现生物利用度和效力,还优选形成每种原花青素的表儿茶素单体数目在2-5之间。 更具体地,向患者施用分离的表儿茶素 - (4-8) - 表儿茶素 - (4-8) - 表儿茶素 - 没食子酸酯(没食子酸偏高糖酸盐)。
