In spite of mature processing techniques and the large availability of raw materials having sufficient quality, there is no study about the relation between the chemical components and material pretreatment method of ginger oleoresin extracted by supercritical fluid CO2. In order to obtain high content of effectual compositions in ginger oleoresin, Ginger was dehydrated by vacuum freeze–drying method and extracted by Supercritical CO2. The components in the extracts were quantified and qualified using Gas Chromatography-Mass Spectrometry method. Same studies were also done with the sun-dried ginger. The results show that the main components are different in the two samples. In the freeze-dried sample, zingerone is the highest substance at 19.472%, pungency compounds are the main components at53.920 %, and the content of sesquiterpene is 20.041%. By comparison, in the sun-dried sample, the content of bisabolene is 26.328% that is the highest, the pungency components are 24.832%, and the main components are sesquiterpene at 56.627%.
