The effects of rosemary extract (RE) and tert-Butylhydroquinone (TBHQ) on the storage stability of radish seed oil were studied according to the change of the acid value, peroxide value, tocopherol and sulforaphene in radish seed oil. The results showed that under conditions of accelerated oxidation by (60±1) ℃, the storage stability of the radish seed oil with antioxidants could be significantly improved, among which TBHQ was better than RE. Besides, RE and TBHQ had a synergistic effect on antioxidation. The compound of 0.01% RE and 0.01% TBHQ had a better antioxidation effect than 0.07% RE and 0.02% TBHQ respectively, which recommended it can be a suitable antioxidant of radish seed oil.
