Abstract

Cinnamon Bark (“Keihi”) is an important crude drug used in Kampo-medicine. Recently, powdered cinnamon bark formulation was approved as an “efficacious treatment for dry mouth, thirst, and diabetes,” and it became possible to commercialize the product as an over-the-counter (OTC) agent. To obtain this approval, the examination of quality control-related characteristics is necessary and, so, we considered developing a testing method. Therefore, we established a quantitative method for (E)-cinnamic acid and coumarin determination. In particular, it is important to establish a quantitative method for coumarin because its association with hepatic injury is a concern.
