For the purpose of utilizing fish-wastes, we determined aqueous vitamines in those materials and found that the liver of Japanese star-gazer (Uranoscops japonicus HOUTTUYN) contained a large amount of anthranilic acid and its derivative. The summary of the experi-mental results are described below. (1) The anthranilic acid content of japanese star-gazer liver is from twenty to fifty times as much as those of other fishes or rats. While the nicotinic acid content is lower than those of other kinds. (2) The anthranilic acid derivative described above is easily hydrolized by NH2SO4 at 80°C in 30 minutes and yields free anthranilic acid and other component not yet clear. (3) The derivative seems to be a compound which combines with some component through the amino group, for the test by Ehrlich reagent is negative and the color of quinhydrone reaction is yellow, while the former test becomes positive and the latter reaction produces red after hydrolysis.
