The antioxidantive effect of propyl gallate (PG), vitamin E and the mixture of butylhydroxyanisole (BHA) and dibutylhydroxytoluene (BHT) (BB, mole ratio 1∶1) on chaenomeles sinensis seed oil (CSSO) were investigated by Schaal-oven method, and their capacities of DPPH scavenging free radical were studied. The results showed that BB had the strongest antioxidant activity, followed by VE and PG. In the short time, DPPH free radical scavenging rate showed that BB> VE > PG in both polar part and nonpolar part of CSSO. Therefore, BB was the most suitable antioxidant for the oil.
