Radical scavenging activity (%) of fucoidan extracted from F. hermonis (FUFe).
| FUFe (µg/mL) | RSA% |
|---|---|
| 50 | 18.1 ± 4.2 |
| 75 | 26.6 ± 9.2 |
| 100 | 36.4 ± 9.1 |
| 200 | 60.5 ± 11.2 |
| 300 | 72.8 ± 5.1 |
| 400 | 75.7 ± 4.9 |
| 500 | 75.7 ± 4.2 |
| IC50 = 157.6 ± 3.3 µg/mL | |
RSA = radical scavenging activity (%) = [(absorbance of control − absorbance of sample)/(absorbance of control)] × 100. IC50 = The concentration of compound that affords a 50% reduction in the assay. Values represent mean ± S.D. from triplicate experiments.
