• The present paper deals with the determination of the Ascorbic acid in various organs of marine animals (Table 1 and 2) and in the marine products (Table 3), using TILLMAN'S 2•6-di-chlorphenol-indophenol titration. The materials were grounded with trichloracetic acid, extract-ed with 5% trichloracetic acid solution, and were filterd (method of BIRTH, HARRIS and RAY). 0•05 c.c. of the pigment solution was titrated with the filtrate. The Tillman's solution was al-ways titrated with the crystallised ascorbic acid. The mean value of the two titrations were summarised in Table 1-3. The ascorbic acid is present in various organs of the fish, the crus-tacea and the mollusca. Of these organs, the spleen, the lens and the kidney are richest in the ascorbic acid and muscle is poorest in it. "Asakusanori", the commercial preparation of the seaweed Porphyra tenera, is rich in it, ca 800mg%.
