Abstract

By anatomical and chemical investigations of Acori rhizomes collected in Japan, the followings were clarified. (1) Anatomically, Acorus gramineus and A. calamus were clearly distinguished from each other by plotting the maximum number of parenchyma cells around an intercellular space against the maximum diameter of fiber bundles. (2) Gas chromatograms of essential oils of A. gramineus always showed peaks of phenylpropanoids mainly consisting of Z- asarone, but did not show any peak of sesquiterpenoids. (3) In the case of essential oils of J. calamus, two chemotypes, type A (consisting mainly of Z- asarone) and type B (consisting mainly of a mixture of sesquiterpenoids), were observed, with some being their intermediates, but they all contained peaks of sesquiterpenoids. Thus, A. calamus and A. gramineus were distinguishable by the presence or absence of sesquiterpenoids in their essential oils.
