Among all the experiments, this study focused on the storage conditions by changing storage time, temperature, light and storage containers with different colors to explore the changes of main components such as α-terpinene, γ-terpinene, terpinolene, terpinen-4, 1,8-cineole and p-cymene in tea tree oil.to find the best storage conditions for obtaining the quality of tea tree oil. 　　The results show that the components of tea tree oils were susceptible to locations, growth period, leaf age, flowering period, storage time of the leaves after harvesting and extraction methods of essential oil. Therefore, it is necessary to uniform the conditions according to the requirements to maintain the quality of essential oil during extraction. 　　In terms of storage conditions, time has the greatest effects on the composition of essential oils. Followed by temperature and containers, which noticeably affected the proportion of α-terpinene, γ-terpinene and p-cymene. 　　According to the results, the best conditions for maintaining the stability of the components during the storage of essential oils for one year were kept in a low temperature (freezing) and brown container.
