Distribution of homarine in muscle and vicera was polarographically studied in some mollusca and crustucea to give the following results. 1) The 1st reduction wave of synthetic homarine•HCI was separated refinedly from the 2nd wave in the electrolyte of acidic buffer (Fig. 1, D and E). 2) A linear relation was found between the diffusion current of the 1st wave and the concentration of synthetic homarine•HCl (Fig. 2). Thus homarine in extracts from tissues was also estimated by measuring the current of the 1st wave, but not the 2nd wave (Fig. 1, C). 3) Homarine content seemed to be higher in liver tissues than in the other tissues. As far as content of homarine in several muscles was estimated in this experiment, the content of homarine in Penaeus japonicus was the highest (0.11% on wet basis), and 0.03-0.07% of homarine (on wet basis) was contained in tissues of other species, but very few in Venerupsis philipinarum and Corbicula leans (Table 1).
