%X The volatile oil from pine needles of <i>Cedrus deodara</i> was extracted by water-steam distillation and analyzed by GC-MS. The antioxidant activity of volatile oil was evaluated by DPPH&#183;, ABTS&#183; and &#183;OH scavenging capacity with V<sub>C</sub> 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&#183;, ABTS&#183; and &#183;OH in a concentration fashion. When the scavenging rate against DPPH&#183;, ABTS&#183; and &#183;OH of volatile oil was 50%, the contents of volatile were 0.30, 0.22 and 0.96 μg&#183;mL<sup>-1</sup>, respectively. The volatile oil from pine needles of <i>C.deodara</i> contains a variety of chemical composition of application value with a certain antioxidant activity.
