“…Hereby, it is highlighted the nutraceutical potential that this phylum/class represents [ 39 ]. Seaweeds have been seen as a feedstock for bioactive molecules that can be incorporated in the daily diet as a supplement in order to promote human health, thus being considered nutraceutical food products [ 40 ].…”

Presently, there is a high demand for nutritionally enhanced foods, so it is a current challenge to look at new raw food sources that can supplement beneficially the human diet. The nutritional profile and key secondary metabolites of red seaweeds (Rhodophyta) are gaining interest because of this challenge. In this context, the possible use of the red seaweed Chondracanthus teedei var. lusitanicus (Gigartinales) as a novel nutraceutical source was investigated. As a result, we highlight the high mineral content of this seaweed, representing 29.35 g 100 g−1 of its dry weight (DW). Despite the low levels of calcium and phosphorus (0.26 and 0.20 g 100 g−1 DW, respectively), this seaweed is an interesting source of nitrogen and potassium (2.13 and 2.29 g−1 DW, accordingly). Furthermore, the high content of carbohydrates (56.03 g 100 g−1 DW), which acts as dietary fibers, confers a low caloric content of this raw food source. Thus, this study demonstrates that C. teedei var. lusitanicus is in fact an unexploited potential resource with the capability to provide key minerals to the human diet with promising nutraceutical properties.

The objective of this study is to assess the chemical composition, nutritional values, and bioactivities of four macroalgae from the Egyptian Red Sea coasts using standard methods. Of these, three Rhodophyceae species, Digenea simplex (D. simplex), Laurencia papillosa (L. papillosa), and Galaxaura oblongata (G. oblongata), and one Phyaeophyceae species, Turbinaria decurrens (T. decurrens), were selected. The results of proximate and chemical composition analyses based on the algal dry weight (DW) showed that carbohydrate content was the highest, ranging from 32.47 ± 1.03% to 45.5 ± 1.23%. Other algal constituents, including ash, protein, moisture, sulfate, lipid, phenolics, and flavonoids, have contents that depend on the algal species. Besides, HPLC analysis revealed that each algal extract contained varying amounts of nine phenolic acids. Atomic absorption spectrometry, the HPLC-Pico-Tag method, the ion chromatography technique, and GC/MS analyses were used to determine the chemical profiles of the elemental, amino acid, halide, and fatty acid of each algal extract. Bioactivities revealed that both the •DPPH and ABTS assays showed that all the algae studied had a significant ability to scavenge free radicals in a dosage-dependent way. They also had strong selective cytotoxic activity against HEPG-2 and HCT-116 cell lines, but only weak activity against MCF-7 and A549 cell lines. Finally, our findings suggested that the selected algae might be efficiently used as nutraceuticals and functional foods, indicating an increase in their proliferation.
