ISOLATION OF D-CYSTEINOLIC ACID FROM A STARFISH, ASTERINA PECTINIFERA

Tsutomu Yoneda, Katsuji Yoshimura

Abstract

1. The compound isolated from starfish, Asterina pectinifera, was identical with D-cysteinolic acid which was obtained from seaweeds by previous workers. 2. Amberlite IR-4B was pretty effective for the separation of taurine and the compound. The authors are grateful to Dr. M. Fujino, Laboratory of Takeda Chemical Industries, Ltd., for elementary analysis.
