A COMPARATIVE STUDY ON THE ANTIOXIDANT ACTIVITY OF EXTRACTS OF Lobophora variegate Less AND Codium tomentosum STACKHOUSE Authors: R. Rabecca And A. Doss*
ABSTRACT
Objective: In-vitro antioxidant activities of two selected Indian algal species viz., Lobophora
variegata (brown algae) and Codium tomentosum (green algae) were evaluated.
Methods: DPPH, Hydroxyl, ABTS, Superoxide and Reducing power of crude extracts
(petroleum ether, Benzene, Ethyl acetate, Ethanol and Methanol) were determined.
Results
The antioxidant activities of the extracts revealed that they inhibited more than 60% of
DPPH, Hydroxyl, ABTS, and Superoxide radicals. The radical scavenging activity, the
reducing power increased with the concentration of the extracts. Depending on the type of
extract and the antioxidant tests, the 50% inhibitory concentration (IC50) ranged from 20.73
to 32.47 ug/ml. The results showed that all of the extracts had antioxidant properties, with C.
tomentosum methanol having the highest antioxidant activity.
Conclusion: The present study suggests that C. tomentosum could be considered during
diseases from oxidative deteriorations.
