A Potential Commercial Source of Fucoxanthin Extracted from the Microalga Phaeodactylum tricornutum

Fucoxanthin, one of the main marine carotenoids, is abundant in macro- and microalgae. Here, fucoxanthin was isolated and structurally identified as the major caroten- oid in the diatom Phaeodactylum tricornutum through chromatographic and spectroscopic methods, such as liquid chromatography-positive-ion atmospheric pressure chemical ioni- zation/mass spectroscopy and nuclear magnetic resonance. This pigment was quantified by reverse-phase...
