“…The reversed-phase liquid chromatography (RP-HPLC), in which the analysis requires a non-polar stationary phase and a polar hydro-organic mobile phase [126], increases the retention with the hydrophobicity of the solutes, the hydrophobicity of the stationary phase, and the polarity of the mobile phase [127,128]. Thus, the separation is accomplished through the partitioning process and the adsorption of the compounds [129].…”

Seaweeds have attracted high interest in recent years due to their chemical and bioactive properties to find new molecules with valuable applications for humankind. Phenolic compounds are the group of metabolites with the most structural variation and the highest content in seaweeds. The most researched seaweed polyphenol class is the phlorotannins, which are specifically synthesized by brown seaweeds, but there are other polyphenolic compounds, such as bromophenols, flavonoids, phenolic terpenoids, and mycosporine-like amino acids. The compounds already discovered and characterized demonstrate a full range of bioactivities and potential future applications in various industrial sectors. This review focuses on the extraction, purification, and future applications of seaweed phenolic compounds based on the bioactive properties described in the literature. It also intends to provide a comprehensive insight into the phenolic compounds in seaweed.

“…Considering the polarity of the solvents involved in the extractions with water (1.000), ethanol (0.654), and acetone (0.355) (Reichardt & Welton, 2010), it is clear their influence on the extraction methods. Knowing the fractions with the best responses to the extraction of antioxidant compounds, one can calculate the volumetric proportion employed in each seed, according to Snyder (1968). The composition obtained as the best response for the unfermented seeds (45% water, 20% ethanol, and 35% acetone) showed 0.705 of polarity, while for the fermented seeds (48% water, 14% ethanol, and 38% acetone) showed 0.706, very close numbers.…”

Materials and methods ReagentsFolin-Ciocalteau reagent, gallic acid, quercetin, 2,2-diphenyl-1-picrylhydrazyl (DPPH), 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid (Trolox), 2,4,6-tripyridyl-1,3,5-triazine (TPTZ), 2,2-Azinobis(3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt (ABTS), standard nonadecanoic acid methyl ester (19:0) and trans-resveratrol internal standard were from Sigma-Aldrich. All other reagents were of analytical grade. SamplesUnfermented Bordo seeds were obtained from an industry in the city of Toledo, Paraná State, Brazil, before fermentation process. Fermented seeds were obtained at a winery located in Quatro Pontes municipality, Paraná State, Brazil, after fermentation process. The seeds were separated from the peels and peduncles, washed, sun-dried, sieved, packed in vacuum, and stored at room temperature.
