Forty-eight samples of Cinnamon Barks obtained in the market in Japan were evaluated according to the provisions under the General Rules for Crude Drugs of the Pharmacopoeia of Japan and were also assayed for the amounts of six components, cinnamaldehyde (1), cinnamic acid (2), cinnamyl alcohol (3), cinnamyl acetate (4), eugenol (5) and coumarin (6), and total tannin. The results revealed that the qualities of Kannan Cinnamons (Guangnan Rougui) and Toko Cinnamons (Dongxing Rougui), both from China, were similar to each other, but different from that of Vietnamese Cinnamons (Yuenan Rougui). Those Vietnamese Cinnamons with the total tannin contents about the same as those in Chinese Cinnamons contained more lipophilic components than Chinese Cinnamons. Although three of the 11 Vietnamese Cinnamons had higher total ash contents, it was concluded that Vietnamese Cinnamons have high quality. High correlation was observed between the amounts of ether-soluble extract, those of essential oils and the total amounts of 1-6 in the 43 samples of 48 commercial Cinnamon Barks from China and Vietnam. Therefore, determination of ether-soluble extract content, which is more exact than determination of essential oil content, may be used as a substitute for the essential oil content assay of Cinnamon Barks.
