Flavonoid metabolite 3‐(3‐hydroxyphenyl)propionic acid formed by human microflora decreases arterial blood pressure in rats

There are reports of positive effects of quercetin on cardiovascular pathologies, however, mainly due to its low biovailability, the mechanism remains elusive. Here, we report that one metabolite formed by human microflora (3-(3-hydroxyphenyl)propionic acid)relaxed isolated rat aorta and decreased arterial blood pressure in rats.
