“…MAAs in G. longissima were analyzed firstly by Torres et al [45], but they identified asterina-330, palythinol, palythene, and usujirene. However, similar concentration and composition (porphyra-334, shinorine, palythine, asterina-330, and palythinol, and a concentration around 1 mg g −1 ) have been shown in this species by other authors [31,43,44]. Finally, concentration and composition of Porphyra species previously published did not differ from the results presented here.…”

“…The concentration in this species was very similar to our work. Álvarez-Gómez et al [31] found four MAAs, but the concentration was much lower than those presented in this work. In another article, similar concentration and composition to that in our work were found [43,44], around 1 mg g −1 , and porphyra-334, shinorine, palythine, asterina-330, and palythinol.…”

“…In order to study the influence of distilled water, as a solvent of extraction in MAA analysis, four Rhodophytes were selected based on their medium-high MAA contents and their different MAA profiles [17,31,32]: Agarophyton vermiculophyllum, Crassiphycus corneus, Gracilariopsis longissima, and Pyropia leucosticta. We selected different procedures and two HPLC columns that are commonly used for MAA analysis in order to elucidate which procedure would be the best option for the isolation, identification, and quantification of MAAs for cosmetic purposes.…”

Mycosporine-like amino acids (MAAs) have gained considerable attention as highly active photoprotective candidates for human sunscreens. However, more studies are necessary to evaluate the extraction efficiencies of these metabolites in cosmetic compatible solvents, as well as, their subsequent HPLC analysis. In the present study, MAA extraction using distilled water and 20% aqueous methanol in four Rhodophyta was investigated. Different re-dissolution solvents and a C8 and C18 columns were tested for the HPLC analysis. Porphyra-334, shinorine, palythine, palythine-serine, asterina-330, and palythinol were identified by HPLC/ESI-MS. The separation of these MAAs were improved employing the C8-column, and using methanol as re-dissolution solvent. Regarding total MAAs concentrations, no differences between the two solvents were found. The highest MAA amounts were observed injecting them directly in the HPLC. According to these results, distilled water could be an excellent extraction solvent for MAAs. Nevertheless, the re-dissolution in pure methanol after dryness would be the best option for the qualitative analysis of the most common MAAs in these red algae. Our results entail important implications regarding the use of red macroalgae as promising candidates as environment-friendly sources of natural sunscreens. coefficients (ε = 28,100-50,000 L·mol −1 ·cm −1 ). They are secondary metabolites capable of absorbing UV radiation with the maximum absorbance between 310 and 365 nm [15][16][17]. MAAs have a general structure that consist of cyclohexenone or cyclohexenimine chromophores conjugated with one or two amino acids that are responsible of UV absorption [18]. The high photostability of MAAs over a wide range of temperature and pH, together with their antioxidant properties, make them promising metabolites in the biotechnology industry. These compounds are recognized as strong UV-absorbing molecules that can be used as an active ingredient in sun-care cosmetic products, therefore could be a potential supplement of chemical filters just used in sunscreens, also due to the fact that they could satisfy consumers who want the incorporation of natural ingredients. Additionally, MAAs could be effective against actinic erythema, but can also protect the humans against other biological effects such as immune suppression or photo-oxidative damage [11,[19][20][21][22][23][24][25]. So, MAAs are promising functional ingredients used for novel cosmeceuticals (cosmetic products with health benefits). In fact, MAAs have already been commercialized as Helioguard®365. This cosmetic reagent contains the MAAs, shinorine and porphyra-334, extracted from the red alga Porphyra umbilicalis and has been successfully commercialized as a natural and safe sunscreen compound. Nowadays, the MAA extraction protocols differ in type of solvents, temperature, and extraction times. The MAA extraction efficiencies and concentrations are affected by these conditions [26][27][28][29]. A variety of extraction and separation methods for MAAs have been...

“…Among them, the total MAAs contents in 323 red algae were determined, and their MAAs contents were usually higher compared with macroalgal Chlorophytes and Phaeophytes [2][3][4][5]40,65]. For example, some members of orders Bangiales [5,40,65], Gracilariales [3,32,66], Gigartinales [5,40,42], and Gelidiales [48,67], their total MAAs contents ranges from 2 mg/g DW to nearly 20 mg/g DW. Of course, there were also many macroalgal Rhodophytes with lower total MAAs contents, such as Actinotrichia fragilis [5], Asparagopsis taxiformi [5], Galaxaura oblongata [5], Gelidium corneum [68], and Georgiella confluens [3], etc.…”

Distribution, Contents, and Types of Mycosporine-Like Amino Acids (MAAs) in Marine Macroalgae and a Database for MAAs Based on These Characteristics

et al. 2020

View full text Add to dashboard Cite

Mycosporine-like amino acids (MAAs), maximally absorbed in the wavelength region of 310–360 nm, are widely distributed in algae, phytoplankton and microorganisms, as a class of possible multi-functional compounds. In this work, based on the Web of Science, Springer, Google Scholar, and China national knowledge infrastructure (CNKI), we have summarized and analyzed the studies related to MAAs in marine macroalgae over the past 30 years (1990–2019), mainly focused on MAAs distribution, contents, and types. It was confirmed that 572 species marine macroalgae contained MAAs, namely in 45 species of Chlorophytes, 41 species of Phaeophytes, and 486 species of Rhodophytes, and they respectively belonged to 28 orders. On this basis, we established an open online database to quickly retrieve MAAs in 501 species of marine macroalgae. Furthermore, research concerning MAAs in marine macroalgae were analyzed using CiteSpace. It could easily be seen that the preparation and purification of MAAs in marine macroalgae have not been intensively studied during the past 10 years, and therefore it is necessary to strengthen the research in the preparation and purification of MAA purified standards from marine macroalgae in the future. We agreed that this process is not only interesting, but important due to the potential use of MAAs as food and cosmetics, as well as within the medicine industry.

Development of food packaging bioactive aerogels through the valorization of Gelidium sesquipedale seaweed

et al. 2019

This study presents the valorization of the Gelidium sesquipedale seaweed for the development of bioactive aerogels with interest in food packaging applications. The raw seaweed was used to extract cellulose, highly crystalline (Xc∼70%) and high aspect ratio (∼40) nanocellulose and an agarbased extract, rich in polyphenols and with antioxidant capacity. Subsequently, pure PVA and hybrid aerogels containing cellulose and nanocellulose were produced by a physical cross-linking method. The presence of hydroxyl groups provided by the high aspect ratio of nanocellulose promoted the interactions with water and facilitated the accessibility of moisture towards the interior of the aerogels, hence generating high water sorption capacity materials. The agar-based extract was then incorporated into selected formulations and the release in hydrophobic and hydrophilic food simulant media was investigated. Pure PVA aerogels dissolved in aqueous media, resulting in an immediate release of the bioactive. Interestingly, the hybrid aerogels containing cellulose and nanocellulose preserved their integrity and provided a more gradual release. Although the hybrid aerogels presented similar release profiles during the first 48 h, the presence of nanocellulose led to greater release values after more prolonged times. This shows the promising properties of hybrid PVA/cellulose/nanocellulose aerogels as matrices for the controlled release of bioactive compounds in food systems, which could be of interest for the development of bioactive packaging structures.
