Sažetak
Seaweeds are a wide group of marine organisms that produce phytochemicals as a response to the harsh environment they live and grow in. These phytochemicals have shown various biological activities such as antioxidant, antibacterial, antiviral, antitumor, immunomodulatory, antidiabetic, and others. Among bioactive compounds, seaweed phenolics, a group ranging from simple to highly complex compounds that have an aromatic benzene ring and one or more hydroxyl groups, have shown very promising antioxidant potential. This study aimed to determine the phenolic contents and antioxidant activities of brown (Colpomenia sinuosa and Dictyota dichotoma), red (Asparagopsis taxiformis and Jania rubens) and green (Codium fragile and Flabellia petiolata) seaweeds harvested from the Adriatic Sea. Besides, the two novel green extraction methods, ultrasound-assisted extraction (UAE) and microwave- assisted extraction (MAE), were tested to determine the extraction effect on the antioxidant activity of the seaweed extracts. Three different assays, ferric reducing/antioxidant power (FRAP), 2, 2-diphenyl-1- picrylhydrazyl radical scavenging ability (DPPH), and oxygen radical absorbance capacity (ORAC) were used to determine the antioxidant potential of seaweed extracts. The TPC of extracts ranged from 119, 17 to 688, 89 mg gallic acid equivalents per liter of extract (GAE/L). The highest antioxidant activity measured by DPPH was found in C. sinuosa, while D. dichotoma had the highest FRAP and ORAC values. The highest TPC and antioxidant activity were found for brown seaweeds when compared to the tested red and green seaweeds. Brown seaweeds’ extracts appear to be more promising for further studies and applications regarding their antioxidant potential.
