The pigments of some further marine phytoplankton species

Abstract
Thin-layer chromatography on plates coated with silica gel and with sucroseglucose (1:1) has been used in the study of the pigments of twenty species of marine phytoplankton from four phyla. A number of apparently new xanthophylls have been found, including a fucoxanthin-like pigment which is the major xanthophyll in an unidentified coccoid alga (Plymouth no. 407).
