Hypothesis
The study investigates the cytotoxic and antioxidant properties of methanolic extracts from seven brown seaweeds.
Conclusion
The brown seaweeds studied exhibit significant cytotoxic and antioxidant activities, suggesting their potential as natural sources of antioxidants.
Supporting Evidence
- The methanolic extracts of seaweeds showed significant cytotoxic activity.
- Stoechospermum marginatum exhibited the highest DPPH radical scavenging activity.
- The total phenolic content varied significantly among the seaweed extracts.
- Seaweeds demonstrated good metal ion chelating properties.
Takeaway
This study shows that some seaweeds can help fight bad stuff in our bodies and might be good for our health.
Methodology
The study used various assays including Brine shrimp lethality assay and DPPH radical scavenging assay to evaluate cytotoxic and antioxidant properties.
