摘要
The carotenoid composition of the deep-water gammaride is reported. Astaxanthin and their derivatives were determined to be major components of the carotenoids (58.4%). Astaxanthin-glycoside-esters comprised 21.6% of total carotenoids. A new carotenoid glycoside ester (CGE) was isolated from the deep water gammaride Acanthogammarus (Brachyuropus) grewingkii and its structure was elucidated. The structures were determined from spectra (H-1-NMR, C-13-NMR, MS, IR) after their isolation and quantification by means of semipreparative RP-HPLC and capillary GC-MS.
