Abstract: The volatile oil from pine needles of Cedrus deodara was extracted by water-steam distillation and analyzed by GC-MS. The antioxidant activity of volatile oil was evaluated by DPPH·, ABTS· and ·OH scavenging capacity with VC as the positive control. Thirty-seven components, accounting for 95.10% of total components, were identified. Olefin hydrocarbon and alcohols were found to be dominant components in the volatile oil. The volatile oil exhibited significant scavenging capacity against DPPH·, ABTS· and ·OH in a concentration fashion. When the scavenging rate against DPPH·, ABTS· and ·OH of volatile oil was 50%, the contents of volatile were 0.30, 0.22 and 0.96 μg·mL-1, respectively. The volatile oil from pine needles of C.deodara contains a variety of chemical composition of application value with a certain antioxidant activity.
