Abstract

concentration. In nitric oxide radical scavenging activity, the ascidians fractions E. viride II showed 64% at 100µgmL -1 and D. psammathodes II showed 72% at 100µgmL -1 concentration. The finding throws light on the higher efficiency of scavenging activity of natural products improved to synthetic drugs. These results indicate that ascidian represent a promising biological resource for derivation of new compounds with antioxidant potential which was far reaching implication in biomedical research and therapeutics.
