Carotenoids in fish - XXXIX. Presence of salmoxanthin in Thymallus thymallus (L.) specimens

Abstract

Column and thin-layer chromatography was. taken ad vantage of to study the occurrence of particular carotenoids in different parts of grayling body. As a result, 20 caro tenoids were identified, in this al so salmoxanthin, i.e. the carotenoid typical of salmonid fishes.

Carotenoids in fish. 51. Cyprinidae-phytophagus: Rutilus rutilus, Rutilus rutilus heckeli, Scardinius erythrophtalmus, Chondrostoma nasus and Rhodeus sericeus amarus

“…The presence ofidoxanthin has been already reported in the Cyprinus carpio (Nagata and Matsuno 1979), arid in the arctic lamprey (Matsuno and Nagata 1979). Czeczuga (1981) noted its presence in the Micropterus salmoides, in the trout (Czeczuga and Chdkowski 1984) and grayling (Czeczuga et al 1985). Idoxanthin is known to be a link in a specific sequence of changes ofl3-caroteneinto astaxanthin (Czeczuga 1988).…”
