Fucoxanthin production by heterokont microalgae

Algal Research, 2017
Abstract Fucoxanthin is one of the most abundant carotenoids in nature. It is a major carotenoid in heterokont and haptophyte groups of algae that includes > 20 thousand species. Fucoxanthin also has many beneficial health effects including anticancer, antihypertensive, anti-inflammatory, and antiobesity effects.

Improved isolation procedure for fucoxanthin

Phytochemistry, 1989
Abstract An improved isolation procedure for crystalline fucoxanthin from brown algae is described, involving partition and chromatography. The method is applicable to peridinin. Partition ratios for fucoxanthin and peridinin are reported.

Chlorophyll triplet quenching by fucoxanthin in the fucoxanthin–chlorophyll protein from the diatom Cyclotella meneghiniana

Biochemical and Biophysical Research Communications, 2012
In this work we present an optically detected magnetic resonance (ODMR) study on the triplet states populated under illumination in the isolated fucoxanthin-chlorophyll light-harvesting complex from the diatom Cyclotella meneghiniana. Evidence for the quenching of chlorophyll triplet states by fucoxanthin is provided, showing that this carotenoid is ...

Naturally occurring stereoisomers of fucoxanthin

Phytochemistry, 1992
Abstract Fast and gentle isolation of crude carotenoids from Fucus serratus, Fucus vesiculosus, Ascophyllum nodosum, Pelvetia canaliculata, Laminaria digitata and Laminaria saccharine followed by HPLC examination suggested that all- E (3 S ,5 R ,6 S ,3′ S ,5′ R ,6′ R )-fucoxanthin is the only naturally occurring stereoisomer in brown algae. Mono-

[Photochemical properties of fucoxanthine].

Biokhimiia (Moscow, Russia), 1976
The ability of fucoxantine for photooxidation by oxygen in a number of organic solvents and for photoreduction by oxorbic acid and phenylhydrazine in pyridine is demonstrated. The reactions are irreversible under common conditions. At the same time fucoxanthine possesses a pronounced ability for photosensitization of red-ox reaction between methyl red ...

Fucoxanthin as an egg‐yolk colorant

Journal of the Science of Food and Agriculture, 1971
AbstractA simple method for the extraction of fucoxanthin from seaweed has been developed. Fucoxanthin, dispersed in gelatin, enhanced the colour of egg‐yolks when fed to laying hens.

Fucoxanthin Ameliorates Inflammation and Oxidative Reponses in Microglia

Journal of Agricultural and Food Chemistry, 2013
Alzheimer's disease (AD) is an irreversible, progressive neurodegenerative disease that slowly destroys memory and thinking skills. In the brains of AD patients, signs of neuronal degeneration are accompanied by markers of microglial activation and inflammation as well as oxidant damage. This study tested the hypothesis that fucoxanthin, which is known

Excited State Properties of Fucoxanthin Aggregates

Chemical Research in Chinese Universities, 2019
The structure and excited state properties of the H- and J-aggregates of the marine carbonyl carotenoid, fucoxanthin(Fx), were studied by various spectroscopic methods, and compared with those of Fx monomers in polar organic solvents. The fluorescent analysis indicated that the higher vibronic states of S2 contribute more to populating the S1 state ...
