Abstract
A new atmospheric pressure chemical ionization mass spectrometry (APCI‐LC/MS) method improved detection and aided characterization of fucoxanthin related carotenoids, revealing the coccolithophoridEmiliania huxleyi(Lohm.) Hay et Mohler (strain MBA 92, Plymouth) to contain a wider range of acyloxyfucoxanthins than reported previously. The diversity is confirmed as arising from differences in the length of the alkanoic acid substituent esterified at position C‐19′. Acyloxyfucoxanthins with substituents of between four and eight carbons at the C‐19′ position have been detected in a culture ofEmiliania huxleyi, where previously only 19′‐butanoyloxyfucoxanthin and 19′‐hexanoyloxyfucoxanthin have been reported in the literature. Novel fucoxanthinol derivatives were also found. The detection of these novel carotenoids inEmiliania huxleyipermits detailed studies of the impact of environmental factors on individual components of the complex pool of fucoxanthin‐type carotenoids in this organism.
