Abstract

β-Carotene, canthaxanthin, lutein, zeaxanthin, isozeaxantbin and astaxanthin ester were separated on column chromatography, using magnesium oxide, alumina, Micro-Cel C and silica gel as adsorbents. Magnesium oxide was found to be the most inert adsorbent; the next was alumina. β-Carotene, canthaxanthin, lutein, zeaxanthin, isozeaxanthin, and astaxanthin ester, separated and purified on a silica gel column, were decomposed or converted to other compounds depending on the duration of time on the column. It was proposed that when zeaxanthin was chrornatographed on a silica gel column, zeaxanthin was converted to another compound which has high absorbance on the ultraviolet side through mutatoxanthin and auroxanthin. When purified on a EDTA pre-treated silica gel as adsorbent, using cyclohexane as the developing solvent, zeaxanthin was stable on that column for 8 h. © 1981, The Japanese Society of Fisheries Science.
