Chemical Composition and Antioxidant Activity of Petroleum Ether Extract of Canarium album

Resumo

Chemical compositions and the relative yield of petroleum ether extract of Canarium album have been investigated by gas chromatography/mass spectrometry (GC/MS). Thirty components, representing 95.05% of petroleum ether extract, were identified. Among these, ethyl linoleate (27.94%), linoleic acid (22.14%), n-hexadecanoic acid (18.74%), and ethyl palmitate (8.63%) are the main constituents, and 12 components are first time reported for C. album. The antioxidant capacity of petroleum ether extract was determined by DPPH· and ABTS+· assay. The results revealed that petroleum ether extract of C. album exhibited good antioxidant activity in both systems. It is the first report on the antioxidant activity of petroleum ether extract of C. album.
