Abstract

Padina tetrastromatica, a brown marine algae species, has garnered attention due to its potential biomedical applications attributed to its rich phytochemical composition. This study aimed to evaluate the antioxidant activities and phytochemical constituents of Padina tetrastromatica extract, shedding light on its potential biomedical implications. The antioxidant activities of Padina tetrastromatica were assessed using various assays including DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging, ABTS (2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid)) radical scavenging, and ferric reducing antioxidant power (FRAP) assays. Results revealed significant antioxidant potential, indicating its capability to neutralize free radicals and mitigate oxidative stress. Furthermore, phytochemical analysis identified a plethora of bioactive compounds in Padina tetrastromatica extract including phenolics, flavonoids, alkaloids, and terpenoids. These compounds are known for their diverse biological activities including antioxidant, anti-inflammatory, and anticancer properties, thus suggesting the potential biomedical applications of Padina tetrastromatica. The findings of this study underscore the importance of Padina tetrastromatica as a promising source of natural antioxidants with potential implications in biomedical fields such as pharmaceuticals, nutraceuticals, and cosmeceuticals. Further research focusing on the isolation and characterization of individual bioactive compounds from Padina tetrastromatica could provide valuable insights into its therapeutic potential and facilitate the development of novel biomedical products.
