Exploring the Bioactive Potential of Marine Algae: Insights from Phytochemical Analysis, GC-MS Profiling, and Antioxidant Evaluation

Abstract

Introduction: While there has been a lot of research on novel compounds derived from natural sources, there is now considerably greater opportunity for study when it comes to marine sources. The immense wealth concealed in marine sources was less known in the past because of a lack of technology. The most recent technological advancements have made gathering and researching marine sources simple. Highly bioactive secondary metabolites that may aid in the development of novel pharmacological drugs are found in marine creatures. The two primary categories of marine algae are macroalgae and microalgae. While macroalgae, also referred to as seaweed, are classified into green, brown, and red algae, microalgae comprise blue-green algae, bacillariophyte, and dinoflagellates. Material and methods: Spongomorpha indica, a green macroalga, has been chosen for this study, and its physicochemical parameters, phytochemical analysis, GC-MS analysis, and antioxidant activity have all been examined. The purpose of this study was to determine whether more research on this seaweed's potential benefits for medical purposes is necessary. Results: The phytochemical tests indicated the presence of potent active constituents like alkaloids, steroids, tannins, and flavonoids; as a result, the study was further extended to GCMS analysis, where seven components were identified, the highest peak and molecular weight of which are all in accordance with WHO guidelines. The physicochemical parameter results were also in line with WHO guidelines. Ultimately, antioxidant activity was assessed using four distinct models, and all results demonstrated a significant amount of antioxidant activity, with superoxide scavenging activity demonstrating the best results. Conclusion: Based on the results, it was determined that Spongomorpha indica contains potent active ingredients with significant antioxidant effects. As a result, the study is now being conducted to examine target-related activity to determine the most efficient way to cure a specific condition.
