Investigation of Spirogyra daedaleoides Czurda in terms of bioactive components

Algae stand out as suitable sources for use in the cosmetic, food and pharmaceutical industries due to their high content of components such as protein, polysaccharide, lipid, vitamin, mineral, amino acid, fatty acid, and carotenoid and due to the bioactive components that they produce. In this study, the bioactive properties of Spirogyra daedaleoides Czurda, located in the Charopyhta phylum of the algae, were examined. This species was isolated from the benthic habitats of the Yeşilırmak River and cultured. Antioxidant properties of Spirogyra daedaleoides was determined with the methods of free radical removal activity (DPPH, 2,2-diphenyl-1-picrylhydrazyl), iron (III) ion reduction power activity (FRAP, fluorescence recovery after photobleaching) and cation radical removal activity (ABTS, 2,2´-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid)). The fatty acids of Spirogyra daedaleoides was determined by gas chromatography analysis, and vitamins were determined by high-performance liquid chromatography (HPLC) analysis. According to the results of antioxidant analysis, the free radical removal activity of Spirogyra daedaleoides, iron ion reduction power activity and cation radical removal activity were found to be high. When the fatty acid percentages of Spirogyra daedaleoides were considered, the ratios of C20:0 Arachidic acid, C16:0 Palmitic acid, C18:3n3 Alpha linoleic acid, C10:0 Caprinic acid and C18:2n6c Linoleic acid were found to be high. Spirogyra daedaleoides was found to be high in Vitamin A and Vitamin E. Spirogyra daedaleoides could be used as natural resources in the cosmetics, food and pharmaceutical industries according to the results.
