Abstract
The aim of this study was to evaluate the effects of extraction solvent (water, ethanol 50%, 70%, 96%) on the antioxidant activity of the leaves of La dong (Phrynium parviflorum Roxb, Marantaceae) via DPPH radical scavenging activity. The results showed that the leaves of La dong extracted by water solvent gave the best effectiveness antioxidant actitvity with a lowest IC50 value (419,61μg/ml) in comparison with those of the other extracts, the IC50 value of the standard ascorbic acid is 7,34 μg/ml. The present study suggested that the water extract of La dong‟s leaves could be a promising source of natural antioxidant
