“…On the other hand, the red alga Gelidium pusillum has high levels of MAAs and polyphenols but there are no available culture techniques. Moreover, numerous studies have pointed out that the first 2 species possess a high capacity to grow by effluent biofiltration (Figueroa et al 2012), so outdoor culture would be economically viable and environmentally sustainable.…”

INTRODUCCIÓNLos organismos marinos, incluyendo las algas y los líquenes, han atraído la atención de muchos investigadores como fuente de compuestos bioactivos debido a sus propiedades, la diversidad de sus moléculas y sus nuevas estructuras químicas que son complejas y difíciles de sintetizar químicamente. Las algas proporcionan una excelente fuente de compuestos bioactivos como carotenoides, polisacáridos, proteínas, lípidos, ácidos grasos, pigmentos, vitaminas, polifenoles y microelementos, entre otras sustancias (Borowitzka Analysis of antioxidant capacity and bioactive compounds in marine macroalgal and lichenic extracts using different solvents and evaluation methods ABSTRACT. Natural extracts of macroalgae are widely recognized for their antioxidant properties. In this work, the antioxidant capacity of various aqueous and hydroalcoholic extracts obtained from red and green marine algae and from one marine lichen collected from different sites in southern Spain (intertidal and estuarine waters) was evaluated by different methods: ABTS free radical scavenging assay, DPPH assay, and β-carotene bleaching method (BBM). Contents of total lipids, total carbohydrates, and UV photoprotectors with antioxidant capacity, such as mycosporine-like amino acids and phenolic compounds, were determined. Among the extraction solvents, the highest extraction yield was observed in H 2 O and 20% MeOH (v/v). The highest antioxidant activity was found in the extracts of the red macroalgae Hydropuntia cornea, Gracilariopsis longissima, Halopithys incurva, and Porphyra umbilicalis, whereas the lowest activity was detected in the green macroalga Ulva rotundata. In general, the antioxidant activity was higher using DPPH than BBM and ABTS. Even so, the ABTS assay is an easy and quick test that provides a comprehensive view of the entire extract in both the lipophilic medium and hydrophilic medium. The antioxidant activity was related to the composition of bioactive compounds and synergistic action is not discarded. The biotechnological use of macroalgal extracts with high antioxidant capacity is discussed.Key words: antioxidants, bioactive compounds, extracts, lichen, macroalgae. RESUMEN.Los extractos naturales de las macroalgas son ampliamente reconocidos por sus propiedades antioxidantes. En este trabajo la capacidad antioxidante de diversos extractos acuosos e hidroalcohólicos obtenidos de algas marinas (rojas y verdes) y de un liquen marino, recolectados en diferentes puntos del sur de España (aguas intermareales y estuarinas), fue evaluada mediante diferentes métodos: método ABTS, ensayo DPPH y método de decoloración del β-caroteno (BBM). Se determinó el contenido de lípidos totales, carbohidratos totales y fotoprotectores de radiación UV con capacidad antioxidante como los aminoácidos de tipo micosporina y compuestos fenólicos.

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...

Production of Mycosporine-Like Amino Acids from Gracilaria vermiculophylla (Rhodophyta) Cultured Through One Year in an Integrated Multi-trophic Aquaculture (IMTA) System

This study evaluates the production of biomass and mycosporine-like amino acids (MAAs) throughout the year in Gracilaria vermiculophylla (Rhodophyta) collected in Ria de Aveiro (Portugal). The algae were grown in outdoor tanks in seawater with the addition of fishpond effluents under two different water flows (100 and 200 L h) in an integrated multi-trophic aquaculture (IMTA) system (tanks 1200 L; 1.5 m) and different algal densities (3, 5, and 7 kg m). MAA content in IMTA seaweeds was significantly affected by the interaction of time and stocking density, but not by the water flow. The highest MAA content was observed in April (about 3.13 mg g DW) followed by May (1.79 mg g DW). Seaweed biomass productivity was higher in May (372.06 g DW m week) than in April (353.40 g DW m week). Four MAAs were identified by HPLC and electrospray ionization mass spectrometry (ESI-MS) in G. vermiculophylla: Porphyra-334, Shinorine, Palythine and Asterina-330. The highest levels of Porphyra-334 and Shinorine were reached from November to January and the Palythine + Asterina-330 from April to August. Taking into account the average biomass and MAA production of G. vermiculophylla growing in this IMTA system (8.56 g of MAA in 18 m culture along 8 months; 35.5% produced in April), a total amount of 71.33 g MAA year could be produced in this system by scaling up to 100 m. MAAs could be further used as photoprotector and antioxidant compounds in cosmetic products.
