FUCOXANTHINE AS A PERSPECTIVE GEROPROTECTOR

Journal of Ural Medical Academic Science
Introduction. From 2000 to 2019, the average life expectancy increased by 6.5 years worldwide, which led to an increase in the number of diseases characteristic of old age. The search for a geroprotector capable of both increasing life expectancy and improving its quality, preventing the development of age-related diseases, is relevant.

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-

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.

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.

[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 ...

[20] Isolation of fucoxanthin and peridinin

1992
Publisher Summary This chapter discusses isolation of fucoxanthin and peridinin. The allenic carotenoids fucoxanthin (I) and peridinin (II) are the two carotenoids biosynthesized in largest quantity. Both carotenoids have the same end groups, five chiral centers, and one chiral axis. The structure of the central chain differs, however—fucoxanthin (I)
