Abstract
Pyropia yezoensis were sampled from Jeonnam in Korea, Jiansu in China and Saga in Japan. Sampled P. yezoensis were analyzed proximate composition by Association official Analytical Chemists(AOAC) method, minerals by ICP-OES and amino acid by amino acid analyzer. Three areas resulted that contents of moisture and crude protein were $8.13{\pm}0.38%$ and $37.25{\pm}1.15%$, and crude lipid, ash and carbohydrate were $2.12{\pm}0.27%$, $7.41{\pm}0.36%$ and $45.06{\pm}1.30%$ respectively. In total minerals, Korea and China were $28300.19{\pm}76.39ppm$and $13945.63{\pm}7.73ppm$, and Japan was $12262.485{\pm}4.38ppm$. Amino acids, Korea and China were $265.28{\pm}0.38mg\;g^{-1}$ and $209.19{\pm}0.19mg\;g^{-1}$, and Japan was $157.61{\pm}0.43mg\;g^{-1}$. Therefore, those substance contents of P. yezoensis are significantly different between cultivation sites. The basic data may used to the environmental and nutritional study of P. yezoensis based on country sites.
