In the course of fundamental studies on the fossilization of the pollen, using the Himarayan cedar pollen (Cedrus deodara LOUD.), the general compositions, the polysaccharides and the soluble components were estimated. From the results of investigations, it has been realized that the general compositions of the Himarayan cedar pollen are not much different from the general compositions of the pine pollen (Pinus densiflora SIEB. et ZUCC. and Pinus Thunbergii PARL.) investigated by Sekine, and that galactan and mannan were contained in a greater amount than the other Polysaccharides. Opinions on the soluble components shall be clarified in future studies
