Liquid chromatography/electrospray ionisation mass spectrometry (LC/ESI-MS) has been employed to identify carotenoid esters present in raw organic extracts of pigmented freshwater microalgae and to gain structural information on these compounds. In particular, acyl carotenoid derivatives of Haematococcus pluvialis and Euglena sanguinea have been characterised by tandem mass spectrometry (MS/MS) in a quadrupole ion trap. ESI-MS/MS allows recognition of the presence of carotenoid esters in… Expand
Profiling Fragments for Carotenoid Esters in Penaeus monodon by Ultra-High-Performance Liquid Chromatography/Quadrupole-Orbitrap High-Resolution Mass Spectrometry.
TLDR
Characterization of the unknown carotenoid esters demonstrates the capabilities of the UHPLC/Q-Orbitrap high-resolution mass spectrometry methodology, which is significant for enriching the carotanoid species in P. monodon. Expand
Separation and identification of fatty acid esters of algal carotenoid metabolites in the freshwater mussel Dreissena bugensis, by liquid chromatography with ultraviolet/visible wavelength and mass spectrometric detectors in series.
LC with photodiode array and APCI-ion trap mass spectrometry has made it possible to tentatively identify 76 carotenyl fatty acid esters (cFAEs) in solvent extracts from Dreissena bugensis, collectedExpand
Sodiation as a tool for enhancing the diagnostic value of MALDI-TOF/TOF-MS spectra of complex astaxanthin ester mixtures from Haematococcus pluvialis.
TLDR
Investigation of ionization and fragmentation of astaxanthin mono- and diester palmitate standards in MALDI-TOF/TOF-MS showed that sodium adduct parent masses gave much simpler MS(2) spectra than radical / protonated parents, which yielded diagnostic polyene-specific eliminations and fatty acid neutral losses.

Optimization of clean extraction methods to isolate carotenoids from the microalga Neochloris oleoabundans and subsequent chemical characterization using liquid chromatography tandem mass spectrometry
TLDR
A novel experimental design was used to optimize the extraction of carotenoids from Neochloris oleoabundans using pressurized liquid extraction with food-grade solvents such as ethanol and limonene using a three-level factorial design and provided mathematical models to predict the behavior of the responses as a function of the factors involved in the process. Expand
An improved method for the separation of carotenoids and carotenoid isomers by LC-MS.
TLDR
The use of a common Syncronis C18 column with strong eluting solvent, here isopropanol, to separate a mixture of 23 carotenoids standards with different structural properties and its ability to resolve isomeric carotenes is significant not only for assessingcarotenoid species, but also for the tracing of metabolic pathways of carotanoids.

Characterization of Shrimp Oil from Pandalus borealis by High Performance Liquid Chromatography and High Resolution Mass Spectrometry
TLDR
A comprehensive characterization of the triacylglycerols and astaxanthin esters that predominate in the shrimp oil is presented by using HPLC-HRMS and MS/MS, as well as 13C-NMR, which offers direct characterization of fatty acid molecules in their intact forms. Expand
Analysis of palmitoyl apo-astaxanthinals, apo-astaxanthinones, and their epoxides by UHPLC-PDA-ESI-MS.
TLDR
Free astaxanthin and its mono- and dipalmitate esters were subjected to two degradation processes in a methanolic model system: light-accelerated autoxidation and hypochlorous acid/hypochlorite (HOCl/OCl(-)) bleaching. Expand
Nitrogen-depleted Chlorella zofingiensis produces astaxanthin, ketolutein and their fatty acid esters: a carotenoid metabolism study
TLDR
Insight into the regulation of microalgal carotenoid biosynthesis as demonstrated in this paper is essential when a large-scale carOTenoid production process is to be optimised or a recombinant C. zofingiensis strain is to been designed with the intention of excessively producing primary or secondary carotanoids.

Carotenoid composition of berries and leaves from six Romanian sea buckthorn (Hippophae rhamnoides L.) varieties.
TLDR
Principal component analysis identified the suitable carotenoid biomarkers characteristic for the Carpathians' sea buckthorn from Romania with contribution to their taxonomic classification and authenticity recognition. Expand
Carotenoid Pigments Composition of Two Commonly Discarded Decapod Crustaceans in Grand Sole and the Galician-Northern Portugal Coast Fisheries
TLDR
The use of these low value by-catch species as a source of carotenoid pigments and fatty acids (e.g., for aquaculture formulations) is a possible alternative to their disposal at sea. Expand
