Seasonal variations in polyhydroxysteroids and related glycosides from digestive tissues of the starfish Patiria (=Asterina) pectinifera

Comp Biochem Physiol B Biochem Mol Biol. 2004 Dec;139(4):581-5. doi: 10.1016/j.cbpc.2004.06.011.

Abstract

Seasonal variations in the concentrations of individual polyhydroxysteroids and related low molecular weight glycosides in pyloric caeca and stomach of the starfish Patiria (=Asterina) pectinifera collected at one location near Vladivostok have been studied. HPLC analysis on the fractions containing these substances showed a fairly constant composition of steroids in digestive tissues of P. pectinifera in spite of small seasonal variations in the relative concentrations of individual compounds.
