Puerarin, an isoflavonoid derived from Radix puerariae, potentiates endothelium-independent relaxation via the cyclic AMP pathway in porcine coronary artery.

Puerarin, an isoflavonoid derived from the Chinese medicinal herb Radix puerariae, has been suggested to be useful in the management of various cardiovascular disorders. The present study examined the effect of acute exposure (30 min) to puerarin on vascular relaxation. Rings from porcine coronary artery of either sex were used.
