Abstract
Wet and fresh ginger grown in Shaanxi was extracted ginger oil by Soxhelt method which used petroleum ether as solvent.Influence of the material agent ratio,extraction temperature and time on ginger oil yield were investigated.All the ginger oil was analyzed of chemical component by GC-MS.The results showed that the optimum time for extraction was 3 h,the extraction temperature was 90 ℃,and the materials ratio(ginger ∶ petroleum ether) was 1 ∶ 6(g ∶ mL).The oil extraction rate under the most favorable conditions was 10.9%,the main ingredient is Zingiberene,curcumene and nerolidol.
