The chemical composition and antioxidant activity of the essential oil of Alseodaphne velutina Chev. (Lauraceae) from Vietnam were investigated for the first time. The essential oil mainly consists of terpenoid compounds and exhibits moderate-to-high antioxidant activity.
Chemical composition and antioxidant activity of the essential oil ofAlseodaphne velutinaChev. (Lauraceae) were investigated for the first time from Viet Nam. Leaf essential oil was hydrodistilled and analysed by GC and GC-MS that totally identified 32 terpenoid compounds (accouting for 89.18% of the total oil) with beta-patchoulene (25.74%) and beta-caryophyllene (12.81%) as two major sesquiterpene hydrocarbons compounds. The antioxidant potential of leaf essential oil was evaluated using DPPH, ABTS and FRAP assays, and revealed a moderate-to-high activity comparable with already known antioxidant standard Trolox.
