This study was carried out to comparison of the contents of general and mineral components between the original sample and water extract in each part of omija. The content of Carbohydrate was highest in endocarps, and that the crude protein and crude lipid in seeds. The contents of K and Mn in the fruits, endocarps, and seeds were all higher than those of the other cations. The content of K and Zn in endocarps were three to four times as much as those of seeds. and the content of Na, Ca, and Cu in endocarps were 1.5 to 1.75 times of seeds. Mineral contents by water extract in each part were ordered as K, Mg, Ca, and Fe. As the percentage of each ion in water extract on the basis of original sample, Fe was the highest ratio of behavior, and Mn was lowest.
