Abstract

The unsaponifiable matter of the fish skin contains much chromogens which react with a ?? timony trichloride (Table 1).<br> Therefore, the authors have determined the vitamin A content in the skin of various fishes after removing the chromogens by the alumina chromatography. On many fishes the vitamin A content of the skin were richer than that of the flesh (Table 2). However, the contrary is the case with eel and lamprey (Table 4). The amount of vitamin A in the skin of flounder was much richer on the eyed side than on the blind side (Table 3).
