The resin oil obtained by hydrodistillation from Dacryodes
edulis G. Don growing in Gabon was analyzed by GC and GC/MS. The major
constituents in the essential oil were sabinene (21.76%), terpinene-4-ol
(19.79%), α-pinene (17.47%) and p-cymene (11.29%). The in vitro
antioxidant activity was investigated with two methods: 2, 2-diphenylpicrylhydrazyl
radical (DPPH) scavenging essay and β-carotene bleaching test. Butylated
hydroxyltoluene was employed as positive control. The essential oil showed
antioxidant and DPPH radical scavenging activities and it displayed the
inhibition of lipid peroxidation. Furthermore, the antimicrobial activity
of essential oil was evaluated using a broth microdilution method. Dacryodes
edulis essential oil exhibited antibacterial activity but it was unable
to inhibit the growth of fungal species tested.
