Abstract:
Owing to their biological characteristics and numerous ways in which they might benefit people, marine algae have drawn the attention of scientists in recent years. This study focuses on polyphenol compounds extracted from Sargassum vulgare and evaluates their antibacterial and antioxidant activities. The polyphenol compound’s free radical scavenging abilities were assessed using nitric oxide, ABTS, DPPH, superoxide anion radical scavenging, hydroxyl-scavenging and hydrogen peroxide scavenging. FT-IR was employed to identify the functional groups present in the polyphenol extraction.
