In the last years, MM have been considered as an important source of bioactive natural compounds, being highlighted the production of bioplastics, biostimulants, biofuels and pigments (Haryatfrehni et al., 2015, Pangestuti and Kim, 2011). Their richness in Natural Pigments (NPs) and the need to replace the synthetic pigments makes the extraction of NPs promising. There are three classes of NPs in MM, namely chlorophylls (Chls), carotenoids and phycobilins (Haryatfrehni et al., 2015, Pangestuti and Kim, 2011). Chl is the major pigment in most of photosynthetic organisms, and there are four kinds (Chl a, Chl b, Chl c, Chl d) in MM, with predominance of Chl a (Haryatfrehni et al., 2015). Carotenoids are considered accessory pigments, and they can be divided into carotenes and xanthophylls (Haryatfrehni et al., 2015). Fucoxanthin, a brown pigment especially present in brown algae, is one of the most abundant carotenoid (Pangestuti and Kim, 2011). Phycobilin is usually found in red algae and it has a more unstable structure, which can be easily damaged by light, heat or chemicals (Haryatfrehni et al., 2015). In short, in red MM (Rhodophyta) the dominant pigments are Chl a and phycobilin, green MM (Chlorophyta) is known to contain Chl a and Chl c and brown MM (Ochrophyta-Phaeophyceae) has fucoxanthin (Fucox) and Chl c (Haryatfrehni et al., 2015).

Recent research is focused on using pigments extracted from marine sources as anticancer agents due to their significant pharmaceutical applications (Manivasagan et al. 2018). Studies have shown the anticancer effects of chlorophyll and its derivatives via assessment of its antimutagenic activities. Fucoxanthin was reported to be effective against various cancers, such as liver, prostate, leukemia, breast, and others. In HepG2 cells, the anticancer activity of fucoxanthin was studied in which fucoxanthin reduced the cell viability by arresting the cell cycle at the G0/G1 phase (Das et al. 2008).
Fucoxanthin
Published in M. Jerold, V. Sivasubramanian, Biochemical and Environmental Bioprocessing, 2019
Fucoxanthin is present in both macroalgae and microalgae. Peng et al. (2011) reported that fucoxanthin is a carotenoid present in brown algae and diatoms. It is the dominant pigment present in macroalgae, coming under class Phaeophyceae, and it also occurs in species coming under the class Bacillariophyceae (diatoms). The characteristic color of brown algae is due to the presence of this pigment, and it contributes over 10% of the estimated total production of carotenoid in nature.

Fucoxanthin, called 3’-acetoxy-5,6-epoxy-3,5’-dihydroxy-6’,7’-didehydro-5,6,7,8,5’,6’-hexahydro-carotene-8-one, is a xanthophyll found in brown algae (Phaeophyceae). It has a specific chemical structure including a distinct allenic link as well as various oxygenic functional moieties such as epoxide, hydroxyl, carbonyl and carboxyl groups [15].
