CHARACTERIZATION OF BIOACTIVE METABOLITES FROM MARINE MACROALGAE COLLECTED FROM VERAVAL COAST OF GUJARATAbstract
Seaweeds are potential sources of bioactive molecules. They are known to be rich sources of proteins, carbohydrates, lipids, vitamins, minerals, and other secondary metabolites. To evaluate the presence of these compounds in marine macroalgae collected from Veraval coast of Gujarat, present studies was carried out. The methanol extract of six macroalgae species (Ulva lactuca, Ulva faciata, Acanthophora dendroides, Gracilaria corticata, Padina tetrastromatica, and Cystoseira indica) was subjected to LCMS/MS analysis which suggested presence of amino acids, sugar, vitamins and phytohormones in algae extracts. The aminoacids and vitamins present in Ulva lactuca (betaine, L-methionine, L-asparagine), Ulva faciata ( L-arginine, L-proline, L-histidine, L-valine, L-Threonine, Dihydrofolic acid), Acanthophora dendroides (L-glutamic acid, L-alanine, L-serine, L-phenylalanine, L-tyrosine, nicotinic acid), Gracilaria coeticata (L-canavanine, L-isoleucine, and L-cysteine) and Padina tetrastromatica (L-Aspartic acid, L-leucine) can be utilized for the development of dietary supplements and proteinaceous food for domestic animals. The sugar present in Ulva faciata (glucosamine), Acanthophora dedroides (D-xylose, D-mannose, D-fructose), Gracilaria corticata (D-Rhamnose, fucose, D-galactose), Padina tetrastromatica (D-glucuronic acid, D-glucose, D-mannuronic acid), and Cystosera indica (arabinose, maltose) can be utilized in food products, cosmetic, gelling and thickening agents. The phytohormones present in Ulva lactuca (6-Benzylaminopurine, jasmonate), Gracilaria corticata (salicylic acid, ethylene), Padina tetrastromatica (Abscisic acid), and Cystosera indica (Indole-3 acetic acid) can be utilized in agriculture as plant growth regulators. Hence, these algae species are essential raw materials for the production of various pharmaceutical and biotechnological products.
