The domestic, edible shellfish, Asari, Venerpis Semidecussata Reeve, collected in winter and transported to the laboratory, taking about one week, was treated with hot water. When the shells were opened, the juice was taken out and analysed. Succinic acid was detected from the portion precipitating by lead acetate, and taurine, tyrosine and leucine from the monoamino acid portion. From the volatile basic portion were obtained ammonia and trimethylamine, from purine portion, adenine, hypoxanthine, from arginine portion, arginine, and from lysine portion, glycocoll betaine, N-methylpyridinium hydroxide. Further, a small amount of histidine was detected in the histidine portion, and two kinds of unknown base were obtained from the arginine portion giving a picrate, m.p. 230-235° (decomp.), and of m.p. 222-225°, and two unknown from the lysine portion, giving aurates of m.p. 91-93° and of m.p. 165-167°.
