Abstract
- The ethanol extract and its solvent subfractions, partitioned by n-hexane (HX), chloroform (CF) and ethylacetate (EA), from Enteromorpha prolifera were measured for antioxidant activities, and a structural identification of the active compound was performed using spectroscopic techniques. The CF fraction showed the most potent 2,2-diphenyl-1-picrylhydrazyl (DPPH) and hydroxyl (OH) radical scavenging activities with strong reducing ability. The DPPH and hydroxyl radical scavenging capacities of the CF fraction were comparable to the capacities of the positive controls, BHA and alpha-tocopherol, at concentrations ranging from 0.25 to 1.0 mg/mL. However, little correlation (r(2) = 0.03-.0.48) was observed between antioxidant activities and total phenolic contents of the extracts. Further fractionation and spectroscopic analysis of the CF fraction suggested that the strong antioxidant activity of the extracts from E. prolifera was because of a chlorophyll compound, pheophorbide a, rather than phenolic compounds.
