The chemical constituents of Alaria crassifolia KJELLM. were studied comparatively in blades and sporophylls. 1. Crude protein, crude fat, crude fiber and ash, except N. F. E., were found to exist more in quantity in sporophylls than in blades, while the total ash exist more in blades than sporophylls. Among the total ash, C03, K, Na, Cl, I and Br were proved to exist more in blades while SO4 more in sporophylls. 2. Alginic acid was proved to exist more in quantity in blades, and laminarin more in sporophylls. 3. The nitrogen compounds were investigated after wan SLYKE's method. As results, mono-amino-form nitrogen was proved to exist plentifully in both blades and sporophylls, while ammonia-form exists more in blades, and diamino-form more in sporophylls.
