%X The peony seed oil was prepared by physical pressing method, and the content of alpha-linolenic acid(ALA) in the obtained peony seed oil and the market peony seed blending oil was determined, and the antioxidant properties of the two peony seed oil were compared and analyzed. The results showed that the content of alpha-linolenic acid in peony seed oil and peony seed blending oil was 43.12% and 29.99%, respectively. The scavenging capacity of DPPH free radical, the scavenging capacity of ABTS, the reducing capacity of Fe<sup>2+</sup> and the scavenging capacity of -OH free radical of peony seed oil were stronger than that of peony seed blending oil, which were 1.29, 1.51, 3.62 and 1.44 times, respectively. It indicated that peony seed oil has stronger antioxidant ability.
