Objective To identify the species of the main carotenoids from Isochrysis zhanjiangensis.Methods Carotenoids from Isochrysis zhanjiangensis were extracted by organic solvent. Carotenoids were separated and purified by column and thin-layer chromatography. The major carotenoids fractions y1, y2 and y3 fromIsochrysis zhanjiangensis were analyzed and identified by thin-layer chromatography (TLC), visible spectrum and high performance liquid chromatography-mass spectrometry (HPLC-MS). Results Fractions y1 and y2 were identified as β-carotene and fucoxanthin, based on the results of TLC, chemical tests and comparing results with standard carotenoids. Combined with the results of visible absorption spectrum, chemical test and LC-MS, the component of y3 was deduced to be fucoxanthinol. Conclusion The major carotenoids from Isochrysis zhanjiangensis are β-carotene, fucoxanthin and fucoxanthinol, respectively.
