The results showed that 22.5μL/L of clove leaf oil had the best preservation effect on peach. After 35 days of stock, the sound fruit rate was 94%, 46.9% higher than compared group. The rotten index and the browning index were 94.1% and 85.2% lower than the control, respectivly, and the treatment could remarkablely reduce the respiration rate and ethylene release, and postponed ethylene release peak and respiration peak 5 and 10d, respectively in comparison with CK, it also delayed the drop of firmness and contents of titrable acids of the peach. When stored for 35d, firmness of control group and 22.5μL/L of clove leaf oil were decreased 60% and 34% compared with initial storage, and the activities of SOD, CAT and POD were enhanced, but the contents of SSC had no obvious difference with control.
