생강을 ether와 hexane으로 추출하여 황색 유상의 crude gingerol extract를 얻었다. 이것을 TLC 분석한 결과 주성분이 gingerol을 함유하고 있음을 확인하였다. 또한 crude gingerol extract가 항산화작용을 한다는 것을 발견하였다. Crude gingerol의 항산화환성은 citric acid 0.04% 첨가시 가장 높았으며, 항산화효과는 BHT, crude gingero1+0.04% citric acid, crude gingerol, BHA, tocopherol순의 결과를 나타내었다.
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 be 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.
