Research Abstract |
Glycyrrhizae Radix has the adverse effect to cause pseudoaldosteronism. It is considered that pseudoaldosteronism is induced by glycyrrhitinic acid (GA) that inhibits 11β-hydroxysteroid dehydrogenase II in renal tubular epithelial cells. The present study reveals that GA cannot pass through the membrane of epithelial cells, but 3-monoglucuronyl glycyrrhietinic acid (3MGA) can actively be transported through the membrane by orgaic anion transporters. It is suggested that the adverse effect of licorice would be occurred not by GA but 3MGA.
