The influence of the storage method of Chimonanthus praecox (L.) Link(CPF)., which were kept under frozen and dryness conditions, respectively, on the quality of essential oils had also been studied. The results showed that the yield and the fragrant components of essential oil from the frozen flower were very similar to the fresh flower. As the frozen time increased, the main fragrant components of CPF kept unchanged, but their contents showed a nonlinear decreasing trend which accelerated significantly after two months of cryopreservation, suggesting that CPF should not be stored for longer than two months under frozen conditions.
