A review on phytoconstituents of marine brown algae

Abstract

Background From the last few years, the development and discovery of bioactive compounds and their potential properties from marine algae have been enhanced significantly. The coastal area is a huge storehouse for propitious algae. It has been the genuine reality that the consequence of marine algae as a source of different compounds is increasing. Main body Numerous advanced research devices are available for the discovery of synthetic compounds but still many researchers are working on natural bioactive compounds to discover their biological properties, which are useful to society. Marine algae are taking the preponderance of consideration from investigators owing to its phenomenon of biological activity like anti-cancer, anti-viral, cholesterol-reducing, and many more. A variety of compounds are collected from algae with specific purposes as they remain in an extremely ambitious and hard state; this condition is responsible for the synthesis of very particularly effective bioactive compounds. The present article is concentrating on the brown algae of the Gujarat coast, phlorotannins, polyphenol, phytosterol from brown algae, and their various applications. The main importance has been given to the secondary metabolites and various applications of marine brown algae. Conclusion From this review, it can be concluded that the prominent bioactive compounds from brown algae can cure many serious diseases. Besides, the potential biological activities of a special bioactive compound may represent the interest in the industry of pharmaceuticals, cosmeceutical, and functional foods.

Sustainable Synthesis of Silver Nanoparticles Using Marine Algae for Catalytic Degradation of Methylene Blue

“…The plausible mechanism of AgNPs synthesis from the extract of Sargassum coreanum is illustrated in Figure 5. The extract of Sargassum coreanum has several phytoconstituents such as polysaccharides, polyphenol contents, and so on [54]. Furthermore, lignans are the key constituents in the marine algae extracts, which encompass metabolites such as ethyl acetate, petroleum ether, and methanolic extract can be responsible for the bioreduction reaction of Ag ions (AgNO3 to AgNPs) and nanoparticle (AgNPs) stabilization [55].…”

Comprehensive metabolomics unveil the discriminatory metabolites of some Mediterranean Sea marine algae in relation to their cytotoxic activities

“…Furtherly, different species of Ecklonia revealed prominent anticancer properties owing to the presence of variable phlorotannin compounds as fucodiphlorethol G, eckol, dieckol, and phlorofucofuroeckol A 4 .…”

“…Indeed, marine algae have served as a treasure trove of structurally variable and biologically active metabolites including polyphenolic compounds, sulfated polysaccharides, fatty acids, steroids, carotenoids, bioactive peptides, minerals and a plenty of others 4 . Many of these phytochemicals possess unique chemical structure and functions which have been never found in the terrestrial counterparts.…”

Occurrence of Marine Ingredients in Fragrance: Update on the State of Knowledge

“…The typical "sea breeze" smell at the beach and/or taste in sea food is the result of a complex mixture of molecules from several chemical classes. Thus, the volatile components released by marine organisms comprise a mixture of chemical classes such as terpenes, hydrocarbons, fatty acids, esters, alcohols, aldehydes, ketones [247], C11-hydrocarbons [248,249], polyphenols and derivatives [250,251], halogenated [252] and sulfur compounds [253,254]. Dimethyl sulfide, mainly distributed in Chlorophyta and in some Rhodophyta [255], is one of the most common and best understood components of seashore aroma; it is marked by a very unpleasant odor including green, sulfur, clammy, boiled cabbage and creamed corn.…”
