“…Fucoxanthin was found to be relatively stable at 80 °C when extracted for 1 h, however, slight degradation was observed at 100 °C when extracted for 1 h. Optimized conditions obtained by Response Surface Methodology (RSM) revealed that at 110 °C using 90% ethanol resulted in 0.39 mg/g of fucoxanthin. In a similar study, Koo et al [100] optimized the pressurized liquid extraction of zeaxanthin from C. ellipsoidea using central composite design. According to their results, the highest recovery of zeaxanthin was obtained using ethanol when compared to n -hexane and isopropanol.…”

Marine microalgae and seaweeds (microalgae) represent a sustainable source of various bioactive natural carotenoids, including β-carotene, lutein, astaxanthin, zeaxanthin, violaxanthin and fucoxanthin. Recently, the large-scale production of carotenoids from algal sources has gained significant interest with respect to commercial and industrial applications for health, nutrition, and cosmetic applications. Although conventional processing technologies, based on solvent extraction, offer a simple approach to isolating carotenoids, they suffer several, inherent limitations, including low efficiency (extraction yield), selectivity (purity), high solvent consumption, and long treatment times, which have led to advancements in the search for innovative extraction technologies. This comprehensive review summarizes the recent trends in the extraction of carotenoids from microalgae and seaweeds through the assistance of different innovative techniques, such as pulsed electric fields, liquid pressurization, supercritical fluids, subcritical fluids, microwaves, ultrasounds, and high-pressure homogenization. In particular, the review critically analyzes technologies, characteristics, advantages, and shortcomings of the different innovative processes, highlighting the differences in terms of yield, selectivity, and economic and environmental sustainability.

“…It is evident that ethanol and in some cases acetone [97], dichloromethane [101] are the most suitable solvents for the PLE of bioactive carotenoids rather than organic solvents such as n -hexane [92,93,95,96,100,102]. Ethanol noted as a “green” solvent minimizes cost and environmental impact.…”

“…Fucoxanthin was extracted most effectively from brown algae, Eisenia bicyclis (Kjellman), by pressurized 90% aqueous ethanol at 383 K [89]. A green microalga, Chlorella ellipsoidea, was subjected to PLE with ethanol at 389 K for the recovery zeaxanthin, this being more efficient than PLE with hexane or isopropanol [90]. Constituents, such as 1,8-cineol and α-terpinenyl, were effectively recovered from cardamom seeds by PLE with 75% aqueous ethanol at 363 K [91].…”

Hot, subcritical and supercritical water, methanol, ethanol and their binary mixtures have been employed to treat fuels (desulfurize coal and recover liquid fuels from coal and oil shales) and to extract valuable solutes from biomass. The properties of these solvents that are relevant to their extraction abilities are presented. Various extraction methods: accelerated solvent extraction (ASE), pressurized liquid extraction (PLE), supercritical fluid extraction (SFE, but excluding supercritical carbon dioxide) with these solvents, including microwave-and ultrasound-assisted extraction, are dealt with. The extraction systems are extensively illustrated and discussed.

“…Optimization of pressurized liquid extraction has been reported for the extraction of zeaxanthin from Chlorella ellipsoidea, (Koo et al, 2012), and the extraction of anthocyanins and biflavonoids from Schinus terebinthifolius Raddi (Feuereisen et al, 2017). The optimized variables that influence the yield are; extraction time, extraction temperature, and solvent.…”

Polypharmacological activities of the biflavonoid fraction of Garcinia kola seed justify its development as a nutraceutical, however, quality assurance of active nutraceutical ingredient (ANI) requires conformance to appropriate standards of composition and quality. It was hypothesized that variation in extraction protocols, as previously reported for the biflavonoid fraction, would lead to variation in extract composition and potency. Computational antioxidant capacity simulation (CAOCS) assay of G. kola extracts obtained by different extraction protocols tested the hypothesis, through incremental addition (250 and 100 µL) of standard antioxidant (AOX) extract solutions in a photometric titration. Preferred model fitting was then statistically selected between mono-and bi-exponential decay. Bestfit reaction constant (k ptt ) was integrated into a metric for ranking antioxidant capacity (AOC) of the extracts. The AOC metric is a molecular descriptor for kinetics of phenolic bond cleavage. Three AOX extracts, namely, ethyl acetate seed extract, kolaviron and acetone seed extract were found to vary in composition, and produced optimal AOC values of 1500/g, 1150/g, and 1050/g respectively. Our findings demonstrated that the composition and potency of biflavonoid fraction of G. kola seed are critically dependent on solvent extraction protocol, and hence, consistent with the hypothesis. CAOCS assay is a suitable analytical tool for ensuring batch-to-batch sameness of ANI prepared from G. kola seed.
