Abstract
Pouzolzia zeylanica was extracted with different solvents (acetone, ethyl
acetate and petroleum ether), using different protocols (cold-extraction and
Soxhlet extraction). To evaluate the antiradical and antioxidant abilities of
the extracts, four in vitro test systems were employed, i.e., DPPH, ABTS and
hydroxyl radical scavenging assays and a reducing power assay. All extracts
exhibited outstanding antioxidant activities that were superior to that of
butylated hydroxytoluene. The ethyl acetate extracts exhibited the most
significant antioxidant activities, and cold-extraction under stirring seemed
to be the more efficacious method for acquiring the predominant antioxidants.
Furthermore, the antioxidant activities and total phenolic (TP) content of
different extracts followed the same order, i.e., there is a good correlation
between antioxidant activities and TP content. The results showed that these
extracts, especially the ethyl acetate extracts, could be considered as
natural antioxidants and may be useful for curing diseases arising from
oxidative deterioration.
