To study the utilization of soft X-ray microradiogram for the evaluation of crude drugs, seven different grades of Cinnamomi veri Cortex were examined. As the result, through the surface image, broad-linear bands due to calcium oxalate crystals in the phloem rays were observed definitely in the lower grade ones, and scarcely in the higher grade. Moreover, comparing with the microradiogram of the stem bark of Cinnamomum verum, higher grade ones corresponded to the bark from slender parts and lower grades to thicker parts. By use of this method jointly with optical microscopic observation was found to be more useful for the histological study of crude drugs. In addition, this method might be superior to the observation of the internal structures of large sized crude drugs without any damages, and gives various interesting informations by treating the drugs beforehand with chemical reagents such as hydrochloric acid.
