Table 4.

Maximum RSA of FU extracted from different species at 500 µg/mL.

FU Source Species RSA at 500 µg/mL Reference
Terrestrial plant Ferula hermonis 75.7% -
Eucalyptus globulus 95.6% [6]
Brown algae Stypopodium schimperi 44.13% [14]

RSA = radical scavenging activity (%) = [(absorbance of control − absorbance of sample)/(absorbance of control)] × 100.
