Yellowish and oily crude gingerol extract was obtained from ginger(Zingiber officinale rose)by ether, ether and hexane extraction. The major component was identified by TLC analysis to he gingerol. The crude gingerol extract thus obtained was found to have antioxidant activity. The crude gingerol extract showed a synergistic antioxidant activity when combined with citric acid. The maximum synergistic effect was observed at 0.04% citric acid. The activity of the antioxidants used was found to increase in the order of BHT, crude gingerol plus 0.04% citric acid, crude gingerol, BHA and tocopherols.
