Abstract
The antioxidant activities of the methanolic extract of Cinnamomum verum barks (CBE) were evaluated with reference to antioxidant
compounds like butylated hydroxyl anisole, trolox and ascorbic acid. By virtue of their hydrogen donating ability, all of the
tested compounds and CBE exhibited reducing power. They were found to be potent in free radical scavenging activity especially
against DPPH radicals and ABTS radical cations. The hydroxyl (
OH) and superoxide radicals ðO
2 Þ were also scavenged by the
tested compounds. CBE also exhibited metal chelating activity. The peroxidation inhibiting activity of CBE recorded using a linoleic
acid emulsion system, showed very good antioxidant activity.
