Bioactivity Measurements of Fucoidan from Six Brown Seaweed Species

Six brown seaweed species from the Pudumadam coast, India, were analyzed for fucoidan content and bioactivity. The dataset contains results from antioxidant, antidiabetic, and cytotoxicity assays for each species. Manisha Prajapati published this research data on figshare in April 2026.

Use Cases

• Compare antioxidant activity (DPPH, HRSA, FRAP IC50 values) across the six seaweed species.
• Model the relationship between fucoidan source species and its α-amylase/α-D-glucosidase inhibition potency.
• Analyze cytotoxic activity data against MCF-7 breast cancer cells for potential anti-cancer agent screening.
• Correlate FT-IR and NMR spectroscopy structural characterization data with measured bioactivity outcomes.

Strengths

• Data includes quantitative IC50 values from three standardized antioxidant assays (DPPH, HRSA, FRAP).
• Covers six distinct brown seaweed species collected from a single geographic region for controlled comparison.
• Provides specific cytotoxicity results against a human breast cancer cell line (MCF-7).

Limitations

• Dataset is very small (51.6 KB), indicating limited sample size and likely low row count.
• Scope is restricted to six species from one coastal location in India, limiting geographic generalizability.
• No raw spectroscopic data or sample-level records are described, only summary assay results.
