Abstract

© 2023 Taylor & Francis Group, LLC.The objective of the current study was to analyze the vital phenolic compounds available in the marine macroalgae (mostly edible) collected from the southwest coast of Turkey, to compute their total antioxidant capacity (TAC) with the cupric ion reducing antioxidant capacity (CUPRAC) and 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonate) (ABTS) assays and to correspond their antioxidant power with high performance liquid chromatography (HPLC) findings. The predominant constitutive phloroglucinol unit of the phlorotannins was the main phenolic component in brown algae species. Among the tested species, those with the greatest phloroglucinol content found by HPLC were Cladostephus spongiosum f.verticillatum (31.62 ± 0.66 μmolg−1), Cystoseira barbata (13.34 ± 0.60 μmolg−1), and Dictyota dichotoma (11.23 ± 0.19 μmolg−1), respectively.
