“…FT-IR analysis confirmed the presence of phenols, carboxylic acids, ketones, ethers, aromatics, amides and sulfonates in several extracts (Table 2). Marimuthu et al (2012) used FT-IR to identify several functional groups such as amides, alcohols, phenols and phosphorous compounds in crude powder of Sargassum wightii, which is corroborated by the present findings. Extracts' GC-MS profile revealed that their main phytoconstituents were propanoic acid, phenol, benzene, dicarboxylic acid, tetradecanoic acid, hexadecanoic acid, eicosanoic acid and nondecanoic acid.…”

Seaweeds have valuable pharmacological properties attributed to the presence of various bioactive compounds. In this study, the phytochemical composition and antioxidant activity of various crude extracts of Hypnea musciformis were determined. Phytochemical screening, Fourier transform infrared (FT‐IR) and Gas chromatography‐mass spectrometry (GC‐MS) analysis were performed to identify the chemical composition of the crude extracts. Antioxidant activity was assayed by total antioxidant capacity for phosphomolybdenum, 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH), 2,2‐Azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic acid (ABTS) and reducing power (RP) assays. The various extracts contained terpenoid, saponin, phlobatannin, cardiac glycosides, phenolics and flavonoids at varying concentrations. FT‐IR results confirmed the presence of phenols, carboxylic acid, ketones, ethers, aromatics, amides and sulfonates. GC‐MS of organic extracts showed that the extracts contain numerous high and low molecular weight compounds. Methanol extract showed the highest phenolic content and antioxidant activity measured by different assays such as phosphomolybdenum (8.2 mg ascorbic acid equivalent), DPPH (79.34%), ABTS (80.21%) and RP (2.36 absorbance at 700 nm) followed by butanol, chloroform and ethyl acetate. Furthermore, methanol and butanol extracts inhibited radical‐induced DNA damage. Practical Applications Hypnea musciformis is widely known source for carrageenan but phytochemical composition and functional activities of this seaweed have not been well studied. Extraction of functional compound depends on solvent and method employed. Results found that the extract showed the presence of diversified phytochemical composition with its potent antioxidant activity at varying degrees. Our results can be used in the future to identify, isolate and characterize the specific compounds responsible for antioxidant activity.

“…In studies reported that the absorption bands at 1100 -1000 cm-1 in the area point out numerous modes such as C-H deformation or C-O or C-C stretching, concern to carbohydrates and polysaccharides 24,25 . The FT-IR spectra of seaweed extracts explore the surfaces of algae had the toxic interaction sites of carboxyl, amino acid and hydroxyl groups of algae 26,27 . Recent report, the bands were reported in diverse materials at to some extent different frequencies at peaks 1147, 1086 and 1025 cm-1.…”

The current study was investigated to explore the biogenic molecules of Sargassum wightii collected from the south east of Tamil Nadu, India. The biogenic molecules extracted from Sargassum wightii by using methanol as a solvent and the analysis was carried out by using UV-Visible spectroscopy and FT-IR. The UV-Visible spectrum of the methanolic extract of Sargassum wightii exposed the existence of the biogenic molecules separated from 200 -1100 nm among the absorption. The incidence of peaks from 234-676 nm discovered the presence of flavonoids and its derivatives. The unprocessed methanolic extract of Sargassum wightii was travelled in to FT-IR and it indicated the being of phenols and flavonoids their functional groups such as alcohol, alkane, carboxylic acids, esters, ethers, alkynes and aromatics. From the results, the future aim of this study is necessary to develop the target site to treat dreadful diseases.

“…As saponinas possuem diversas propriedades, dentre elas, atividade antimicrobiana (XU et al, 2000). Deste modo, a presença de compostos fenólicos, alcalóides, flavonóides, e saponinas, nos extratos bruto de S. wightii sugerem que essa alga pode ser utilizada como antimicrobianos (anti-viral, anti-fúngica e anti-bacteriana), dentre outros efeitos (MARIMUTHU et al, 2012 Candida glabrata e Cryptoccus neoformans (MANIVANNAN et al, 2011).…”

ResumoO melão é da família cucubitáceas, pertence ao gênero Cucumis e apesar de ser originário dos vales do Irã e no noroeste da Índia, apresenta grande relevância para a região Nordeste do Brasil. A cultura do melão sofre com problemas fitossanitários, os quais acarretam a grande perda da produtividade. O declinio da produção pode estar relacionado à ação de microorganismos fitopatogênicos como fungos e bactérias, sendo os fungos os fitopatogénos mais prejudiciais à esta cultura. Atualmente, o controle desses microorganismos é feito com fungicidas químicos, no entanto, sabe-se que esse tipo de controle é prejudicial ao meio ambiente e a saúde humana devido aos resíduos que podem permanecer nos alimentos. Uma alternativa para esse problema é o uso de produtos naturais como, por exemplo, extratos de algas marinhas. A alga Sargassum filipendula pertecente à ordem Phaeophytas, é mais comumente encontrada em regiões tropicais, é imporrtante para as indústrias alimentícias, farmacêutica, cosmética e agronômica. Apesar da grande relevância industrial e da sua vasta aplicabilidade, poucos estudos têm sido realizados com a finalidade de gerar novos produtos oriundos desta alga. Neste contexto, avaliamos a atividade antifúgica do extrato etanólico obtidos a partir de S. filipendula. As amostras foram coletadas no município de Rio de Fogo (RN
