Abstract
Succeeding to the experiment in the previous paper1), comparative studies were carried out on the following attempt to establish that the PRB (polarographically reducible base) isolated from the extracts of dried squid muscle is homarine (N-methyl picolinic acid betaine): 1. PRB-HCl derived from its chloraurate. 2. Synthetic homarine•HCl prepared by the methylation of picolinic acid. 3. Trigonelline, a commercial specimen (N-methyl nicotinic acid betaine, an isomer of homarine). The comparison of the PRB-HCl was made with synthetic homarine•HCl and trigonelline in regard of their absorption spectra, half wave potentials and paperchromatographic behaviors (Tables 1-3 and Figs. 1-4). The result showed that the PRB-HCl and the synthetic homarine•HCl are intirely same m these properties. Also, as the results of elementary analysis of the PRB-chloraurate (in Table 4), the PRB isolated from the extracts of dried muscle was identified as homarine.
