“…Similarly, Aditi, Jaishini, Raisa, Aamna, and Rupali (2020) reported that carotenoids were identified for green microalgae; Spirogyra neglecta, Pithophora oedogonia and Microspora indica, based on Thin-layer Chromatography (TLC) and High-Performance Liquid Chromatography (HPLC) analysis. U. lactuca also presented a significant content of carotenoids in which -carotene recognized as major compounds (11.44 -11.47 %) (Abd El Hafez, Elkomy, Saleh, and Aboul-Ela, 2020). This promising total amount of pigment contents in Chlorophyta make it a perfect target for use as a colorant, antioxidant, antimicrobial and Active Pharmaceutical Ingredient (API) in the future.…”

“…Hence, it can be deduced that oligosaccharides from U. lactuca can be utilized in the making of nutraceutical products and in cosmeceutical to prevent aging problems (Liu et al, 2019). In addition, Abd El Hafez et al (2020) reviewed the antioxidant activity possessed by U. prolifera by the total antioxidant capacity method. From their studies, the total antioxidant capacity exhibited by different solvent extracts, namely hexane, ethyl acetate and methanol extracts, were 0.97 ± 0.09, 1.23 ± 0.04 and 1.63 ± 0.09 mg equivalent ascorbic acid/g dw, respectively, which was due to the polysaccharide, lipid, and protein contents in U. prolifera (Abd El Hafez et al, 2020).…”

Additionally, the pigment contents in Chlorophyta can be beneficial in acting as antioxidants as pigment-like carotenoids can inhibit active radicals (Hidayati, Yudiati, Pringgenies, Oktaviyanti, & Kusuma, 2020).…”

Seaweeds are valuable marine plants that have garnered much attention from the public due to their high bioactive, nutrients and minerals content. Seaweeds have been used in multiple applications, including in cosmeceutical, nutraceutical and pharmaceutical industries. Nevertheless, this review will focus on the bioactive compounds of Chlorophyta and their potential application in nutraceutical and cosmeceutical industries. Chlorophyta are believed to possess a significant amount of nutrients and minerals, sufficient to meet the daily requirements of nutrients and minerals in the human body. Considering the nutritional aspect, deficiency in nutrients may lead to severe ailments, including heart disease, neurological disorder and cancer. The main compounds studied in this review are polysaccharides, proteins, amino acids, lipids, fatty acids, pigments, minerals, vitamins and secondary metabolites. Among all, polysaccharides are the most exploited compounds and used in many advanced applications in the nutraceutical and cosmeceutical industries. This review also offers insights into the beneficial biological properties of Chlorophyta, highlighting their potential in cosmeceutical and nutraceutical applications. Further research is required to highlight the Chlorophyta sp. aquaculture, its extraction method, and the most targeted bioactive compounds from the species. Therefore, the challenge is to increase public awareness of the promising application of this species in the nutraceutical and cosmeceutical industries.

“…Significant efforts should be made to identify and isolate the bioactive compounds that are involved in the antioxidant, antimutagenic, and antiproliferative activities of these seaweed species, particularly in C.sertularioides which showed a high potential for further investigations to propose novel therapeutic biocompounds. Next, Mohamed et. Al.,(2020), shows the results of the present study conclude that macroalgae U. prolifera, collected from the Egyptian Red Sea, have potential bioactive substances with both antioxidant and antibacterial effects and could be used as healthy valuable edible seaweed .…”

Seaweed is the key to developing habitat in deep sea, coastal, and estuarine environments. Seaweed, humans, and animals have been interrelated since the beginning, especially as a food source of fiber, protein, vitamins, antioxidants, and bioactive compounds. Natural antioxidants are seen as a superior and safe method of fighting free radicals. Sources of antioxidants usually come from land plants and rarely from seaweed. Silpau is a seaweed and a local food ingredient in Maluku Province, Indonesia, and has the potential as an antioxidant. Antioxidant and bioactive compounds are needed by humans and animals as antibodies to fight various negative influences from the environment. This research aimed to isolate and characterize active antioxidant compounds and the toxicity of silpau extracts. The extraction of the active compound begins with a single maceration method for 3 x 24 hours with methanol solvent, processing with the partition extraction method for subfraction separation using column chromatography with the silica gel stationary phase and the mobile phase solvent n-hexane: ethyl acetate with a ratio (50: 1 ~ 1: 1) gradient. The sample toxicity was tested using the Brine Shrimp Lethality Test method. The trial activity used the Free Radical Reduction method with 2,2-diphenyl-1-pikrilhidrazil as a reagent. This research succeeded in isolating one bioactive compound from the glare green macroalgae. Based on the phytochemical analysis and FT-IR spectrophotometer, sub-fraction IV was identified as a triterpenoid class of compounds that has an IC50 value of 126,582 μg / ml and is considered an antioxidant.

“…Such survival conditions stimulate the production of an extremely abundant variety of biologically active substances [4][5][6][7]. Secondary metabolites isolated from different alga are playing an important role as lead components, natural medicine or nutraceuticals in drug discovery research and pharmaceutical industries and natural food preservatives [8,9]. Recently, due to the resistance of different pathogenic bacteria and pests to antibiotics and insecticidal agents, finding new active components against these health and environmental problems is one of the major areas of medical and agricultural research.…”

With respect to the potential natural resources in the marine environment, marine macroalgae or seaweeds are recognized to have health impacts. Two marine algae that are found in the Red Sea, Codium tomentosum (Green algae) and Actinotrichia fragilis (Red algae), were collected. Antibacterial and antioxidant activities of aqueous extracts of these algae were evaluated in vitro. Polyphenols from the extracts were determined using HPLC. Fillet fish was fortified with these algal extracts in an attempt to improve its nutritional value, and sensory evaluation was performed. The antibacterial effect of C. tomentosum extract was found to be superior to that of A. fragilis extract. Total phenolic contents of C. tomentosum and A. fragilis aqueous extract were 32.28 ± 1.63 mg/g and 19.96 ± 1.28 mg/g, respectively, while total flavonoid contents were 4.54 ± 1.48 mg/g and 3.86 ± 1.02 mg/g, respectively. Extract of C. tomentosum demonstrates the highest antioxidant activity, with an IC50 value of 75.32 ± 0.07 μg/mL. The IC50 of L-ascorbic acid as a positive control was 22.71 ± 0.03 μg/mL. The IC50 values for inhibiting proliferation on normal PBMC cells were 33.7 ± 1.02 µg/mL and 51.0 ± 1.14 µg/mL for C. tomentosum and A. fragilis, respectively. The results indicated that both algal aqueous extracts were safe, with low toxicity to normal cells. Interestingly, fillet fish fortified with C. tomentosum extract demonstrated the greatest overall acceptance score. These findings highlight the potential of these seaweed species for cultivation as a sustainable and safe source of therapeutic compounds for treating human and fish diseases, as well as effective food supplements and preservatives instead of chemical ones after performing in vivo assays.
