In continuation of the work described in the previous report [This Journal: 72, 69 (1952)], components of four kinds of Sect. Ornus was studied with the following results: Species Location Component Fraxinus borealis Nakai Akita Pref. (northeastern) Aesculin, fraxin, mannitol F. longicuspis S. et Z. Miye Pref. (west central) Aesculin, mannitol Saitama Pref. (eastern) Aesculetin, fraxetin F. sabucina var. pubineavis Nakai Saitama Pref. (eastern) Aesculetin Ishikawa Pref. (northwestern) Aesculetin, fraxin F. sambucina var. velutina Nakai Ishikawa Pref. (northwestern) Aesculetin
This result shows that aesculin or aesculetin was obtained without exception from 12 kinds of domestic Sect. Ornus plants, whereas fraxin is present in the majority of these plants growing wild in Europe. The aqueous extract of these barks show strong fluorescence. Fraxin is present in Aesculus turbinata L. growing wild in Japan (loc. cit.). This shows that the domestic plants contain aesculin in Fraxinus species and fraxin in Aesculus species, which is reverse the case in Europe.
