The aim of this study was to determine the major boactive constituents, trans-cinnamic acid and transcinnamaldehyde,
and anti-oxidative activities of 50% aqueous methanol and water extracts of Cinnamomum burmannii
Blume stem bark. Gas chromatography-mass spectrometry (GC-MS) was used to analyse the extracts. The content of
trans-cinnalmadeyde quantified in the 50% aqueous methanol and water extracts were 50.14 µg/mg and 12.83 µg/mg of
dry extract, respectively. The content of trans-cinnamic acid quantified in the water extract was 49.7 µg/mg of dry extract.
Trans-cinnamic acid was not detected in the 50% aqueous methanol (v/v) extract. The extracts demonstrated in vitro antioxidative
effects with the 50% aqueous methanol extract being more potent than the water extract.
