“…This may be due to the specific compounds in algae (El Modafar et al., 2012; Ammar et al., 2017; Ali et al., 2021), fungi (Sobolev, 2013; Aisyah et al., 2015) or bioprocessed elicitors (Ramakrishna et al., 2017). Metabolite profiling of Sargassum vulgare revealed several bioactive molecules, including multiple acids such as ascorbic acid, gallic acid, palmitic acid and oleic acid (Mahmoud et al., 2019; Abu Ahmed et al., 2021). These acids can subsequently loosen the cell wall.…”

Trans-resveratrol is a natural polyphenolic compound, belonging to the class of stilbenes. It is known for its various pharmacological properties but limited bioavailability. Our objective was to evaluate for the first time the effect of an extract of Sargassum vulgare on resveratrol, piceatannol and piceid production in peanut (Arachis hypogaea) sprouts. Treatments with rising concentrations of seaweed extract were assessed in 'Trabelsia', 'Chanfakhi' and 'American' peanut varieties after 7 days of incubation. Liquid chromatography-mass spectrometry was performed to quantify targeted compounds. Total phenols and flavonoids content, PAL and TAL activity and DPPH radical scavenging activity were also determined. A significant genotype effect was demonstrated, as quite exceptionally, in 'Trabelsia' the resveratrol content was increased by a factor 110 by elicitation with 8% extract. Piceatannol, piceid, TPC, TFC, PAL, TAL, and DPPH radical scavenging activity confirmed the same trend. This study provides a new insight into an effective approach to enable the accumulation of resveratrol and its derivatives in peanut sprouts for use as a functional food.

“…All compounds had antioxidant, antimicrobial, Anti fungi, antiviruses, Antiulcer, anti-inflammatory, and anticancer (Table 5). In similar study of Sudha and Balasundaram, a total of twenty bioactive chemicals have been reported from ethanolic extract of P. pavoica by (GC-MS) analysis [54] In another study of Usha and Rani GC-MS analysis revealed eighteen components in the methanol extract of P. pavonica [67].…”

“…Our results are in agreement with Do et al , who used ethanol (75%) and acetone (75%) to measure total phenolic and total flavonoid. It was concluded that acetone gave a total flavonoid result (0.64) more than ethanol (0.35), but ethanol showed atotal phenolic (1.36) more than acetone (0.87) [53][54].The lowest total carotenoids (0.183), phenolics (0.9), tannins (0.0162), flavonoids (1.875) and sulfated polysaccharides (0.0415) were observed in the EtOAc extract of p. pavonica (Figure 2). The DPPH radical scavenging assay is widely used as a prescreening tool for novel antioxidants derived from natural sources due to its reproducibility and stability [36].…”

In the current study, the extraction of bioactive secondary metabolites from the macroalgae Padina pavonica with different organic solvents were examined. The influence of three different solvents, i.e. ethyl acetate, acetone, and ethanol on the extraction of P. pavonica extracts were analyzed for major phenolic sub-groups, i.e. total phenolics, flavonoids, and tannins as well as total sulfated polysaccharide and carotenoids using spectrometric methods. Meanwhile, the total bioactive secondary metabolites were measured by GC-MS. The antioxidant activities were evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH), and the antimicrobial activities were assessed against different pathogenic bacterial and fungal strains (Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Enterococcus faecalis, and Candida albicans.). The aim of the study was also to find the correlation between the chemical constituents of the extracts and their biological activities. The current study revealed that these extracts exhibit a good antioxidant activity, especially acetone extract, with high reducing capacity (80.58%). Also, the antimicrobial activities for acetone extract was higher than either the ethanol and ethyl acetate organic solvents due to their higher contents in bioactive compounds as reflected from their phytochemical screening and GC-MC. The GC-MS analysis revealed the presence of different phytochemical compounds resulted in 20 peaks for acetone, 14 for ethanol, and 12 for ethyl acetate. The results of this investigation could be interesting for future studies dealing with the application of P. pavonica in marine biotechnology, textile industry, nutrition, and pharmaceuticals for their higher antioxidant as well as antimicrobial activities.

Digenea simplex (D. simplex), an Egyptian marine red macroalga, contains a diverse group of phytochemicals with unique bioactivities. At the same time, the synthesis of nanosuspension (NS) has received increasing interest to optimize the technological aspects of drugs. Thence, the main objective of this work was to use the chloroform extract (ChlE) of D. simplex to prepare its nanosuspension (ChlE-NS) formulation to increase its aqueous solubility, thereby improving its bioactivity. By using FTIR, GC/MS analysis, and phytochemical screening assays, the chemical profiling of ChlE was assessed. NS was prepared by the antisolvent precipitation technique using 1.5% w/v polyvinyl alcohol (PVA). A light microscope, FTIR, particle size distribution, polydispersity index (PDI), and zeta potential (ZP) measurements was used to characterize the prepared NS. Four cancer cell lines were used in the MTT experiment to investigate the anticancer potential of ChlE and ChlE-NS. An apoptotic mechanism was established using acridine orange/ethidium bromide (AO/EB) dual staining, DNA fragmentation, and increased caspase activity. ChlE and ChlE-NS were also evaluated as antioxidants using DPPH and ABTS free radical assays. The results showed that, when compared to ChlE, ChlE-NS had greater cytotoxic activity against the four cancer cell lines. However, results of antioxidant activity showed that ChlE-NS had an IC50 of 36.86 ± 0.09 and 63.5 ± 0.47%, while ChlE had values of 39.90 ± 0.08 and 86.5 ± 0.8% in DPPH and ABTS assays, respectively. Based on the results of this research, D. simplex ChlE-NS may be an effective strategy for enhancing ChlE's cytotoxic and antioxidant activities. Graphical abstract
