Abstract
For the purpose of finding the seasonal variation of the content of green pigments in oysters at each oyster bed as below described, and also the relation between the content of green pigments and that of magnesium, zinc, iron, and copper, the oysters cultivated at Akitsu, Saka and Jigozen, along the coast of Hiroshima, were investigated from January 11 to June 10.Green pigments were estimated by measuring optical density at 660mμ for the solution which was extracted from oysters with hydrochloric acid-acetone (10:90) mixture. Iron was determined by 0-phenanthroline method, and magnesium, zinc and copper were determined by atomic absorption spectrophotometry.The content of green pigments in oysters considerably changes with bed or season. Although the content of these metals considerably changes with oyster bed, any remarkable seasonal change and also any definite interrelation between the content of metals and that of green pigments were not found.
