The crinoid Ptilometra australis Wilton
yields to organic solvents a complex mixture of pigments from which the three
principal components have been separated by chromatography on magnesium
carbonate. These substances have been shown by spectral and chemical
examination to be 1,6,8-trihydroxy-3-(1-hydroxypropyl). anthraquinone,
1,6,8-trihydroxy- 3-(2-hydroxypropyl)anthraquinone, and 1,6,8-trihydroxy-3- propylanthraquinone-2-carboxylic acid. The distinct types
of crinoidal pigments isolated from Comatula species1 and from Ptilometra
australis both conform to the acetate rule and are
probably endogenous in origin. Both
yellow and black specimens of the crinoid Tropiometra
afra Hartlaub also contain the anthraquinonecarboxylic
acid isolated from P. australis.
