Five extracts of ginger (Zingiber offcinale Roscoe) from Shuicheng and Guizhou were obtained by different extraction processes, including steam distillation ginger essential oil, ethanol solvent ginger oil, supercritical CO2 ginger oil, supercritical CO2 ginger essential oil, and supercritical CO2 ginger oleoresin. Their yields were 0.86%, 3.56%, 4.78%, 1.27%, and 3.39%, respectively. The chemical compositions of five extracts were qualitatively normalized by GC-MS, and gingerol compounds were quantified by HPLC. 39, 45, 48, 50, and 46 compounds were detected by GC-MS for five extracts, respectively. The GC-MS chromatograms, 21 components with a content of more than 1% in the chemical compositions by normalization method and the quantitative detection results for gingerols by HPLC were statistically analyzed and compared. Results showed that the chemical compositions of steam distillation ginger essential oil and supercritical CO2 ginger essential oil, ethanol solvent ginger oil and supercritical CO2 ginger oil were similar to each other, and supercritical CO2 ginger oleoresin was different. By supercritical CO2 selective extraction and separation process, one-time could get ginger essential oil with 6-gingerol content of 42.05 mg/g and ginger oleoresin with 170.98 mg/g, respectively, which showed a high separation and enrichment efficiency for gingerols in ginger. By adjusting the extraction process parameters, three extracts of ginger oil, ginger essential oil and ginger oleoresin rich in gingerols could be obtained from ginger by supercritical CO2 extraction. It is the preferred process for the extraction and separation of volatile and fat-soluble bioactive components in ginger.
