“…The total phenolic content of S. obliquus water and ethanol extracts were determined as 48.0 mg GAE/g extract and 22.2 mg GAE/g extract, respectively. Stoica et al [24] used water, ethanol and their mixture in order to determine the total phenolic content of Scenedesmus opoliensis. They reported that the highest total phenolic content was found as 151.5 mg GAE/100 g of dry algal biomass for absolute water solvent, and the lowest total phenolic content was found as 61.4 mg GAE/100 g of dry algal biomass for absolute ethanol solvent.…”

Skin is the largest organ of our body and it protects interior organs against several environmental factors. Hyperpigmentation problem occurs as a result of abnormal melanin accumulation in the skin. A considerable amount of world's population uses skin whitening products. It is known that various algaederived secondary metabolites play an important role in skin problems. Therefore, the tyrosinase inhibitory activities of S. obliquus ethanol and water extracts were evaluated in the present study. Tyrosinase activity was determined spectrophotometrically at 492 nm. The ethanol extract showed the higher inhibitory activity on tyrosinase enzyme (IC50: 0.0270 g/mL) than water extract (IC50: 0.2882 g/mL). This result may have stemmed from the vanillic, ferulic acid and rutin components that were identified by RP-HPLC only in the ethanol extract.

“…Phenolic compounds from macroalgae are part of a diverse and complex group that encompasses simple molecules such as phenolic acid, as well as more complex polymeric structures such as phlorotannins, with up to eight interconnected phloroglucinol units [12,13]. Multiple in vitro studies have demonstrated the efficiency of macroalgal phenolic compounds as antioxidant, antimicrobial and anticancer agents [7,[14][15][16][17][18].…”

Exploring Ultrasound, Microwave and Ultrasound–Microwave Assisted Extraction Technologies to Increase the Extraction of Bioactive Compounds and Antioxidants from Brown Macroalgae

This study aims to determine the influence of (1) ultrasound-assisted extraction (UAE), (2) microwave-assisted extraction (MAE) and (3) a combination of ultrasound–microwave-assisted extraction (UMAE) on the yields of fucose-sulphated polysaccharides (FSPs), total soluble carbohydrates and antioxidants extracted from A. nodosum. Scanning electron microscopy (SEM) was used to evaluate the influence of the extraction technologies on the surface of macroalgae while principal component analysis was used to assess the influence of the extraction forces on the yields of compounds. UMAE generated higher yields of compounds compared to UAE and MAE methods separately. The maximum yields of compounds achieved using UMAE were: FSPs (3533.75 ± 55.81 mg fucose/100 g dried macroalgae (dm)), total soluble carbohydrates (10408.72 ± 229.11 mg glucose equivalents/100 g dm) and phenolic compounds (2605.89 ± 192.97 mg gallic acid equivalents/100 g dm). The antioxidant properties of the extracts showed no clear trend or extreme improvements by using UAE, MAE or UMAE. The macroalgal cells were strongly altered by the application of MAE and UMAE, as revealed by the SEM images. Further research will be needed to understand the combined effect of sono-generated and microwave-induced modifications on macroalgae that will allow us to tailor the forces of extraction to target specific molecules.

“…Polyphenols are recognized as important natural antioxidants and include several thousand compounds with great diversity in structure, which can be divided into ten different main classes according to their basic chemical structure [7,8]. Polyphenols act as antioxidants by single electron transfer and by hydrogen atom transfer [9].…”

The Contribution of Carotenoids, Phenolic Compounds, and Flavonoids to the Antioxidative Properties of Marine Microalgae Isolated from Mediterranean Morocco

et al. 2019

This study aimed to investigate the potential of four sea water microalgae, isolated and cultivated at M′diq Bay in Morocco, as a new source of natural antioxidants. These microalgae belong to different classes, including Phaedactylium tricornitum (Bacillariophyceae), Nannochloropsis gaditana (Eustigmatophyceae), Nannochloris sp (Trebouxiophyceae), and Tetraselmis suecica (Chlorodendrophycea). The antioxidant properties were screened by the use of in vitro assays, namely 2,2-difenil-1-picrylhydrazyl, Ferric reducing antioxidant power, and Ferrous ions chelating activity, and compoundidentification was carried out in methanol and acetone extracts of both dried and fresh microalgae biomass by HPLC–PDA–MS analysis. Among the investigated microalgae, Phaedactylium tricornutum was the richest one regarding its carotenoid (especially all-E-fucoxanthin) and phenolic (especially protocatechuic acid) contents, as well as antioxidant activity (65.5%), followed by Nannochloris sp, Tetraselmis suicica, and Nannochloropsis gaditana, with antioxidant activity of 56.8%, 54.9%, and 51.1%, respectively.
