The volatile oil from ginger by enzyme-assisted steam distillation and its anti-oxidative aetivities were studied. The types of enzyme,enzyme dosage,enzymatie temperature,and enzymatie pH whieh affeet-ed enzyme-assisted extraetion of volatile oil were studied. The anti-oxidative aetivities of volatile oil from ginger were studied by the methods of lipid peroxidation and DPPH radieal seavenging. The result showed that the optimal proeess eonditions were eellulose,enzyme dosage of 2. 0%,enzymatie temperature of 50 ℃,enzymatie pH of 6. 0,enzymatie time of 2. 0 h,steam distillation time of 3. 0 h. Under these eondi-tions,volatile oil yield was 3. 86%. The volatile oil from ginger on lipid peroxidation and DPPH radieal seavenging had a good effeet.
