Abstract

Optically pure dye concentrates of natural sources are prepd. from disintegrated cells of living organisms, having removed insol. pts. The conductivity of the soln., that contains the dye, e.g. of the filtrate is adjusted to 400 ms/cm. to allow the sepn. of individual optically pure dyes by electromigration.
