- Abstract: OBJECTIVE: To optimize the extraction and inclusion processes of ginger oleoresin from Zingiberis Rhizoma Recens. METHODS: Supercritical carbon dioxide extraction was selected to extract ginger oleoresin from Zingiberis Rhizoma Recens. The extraction condition was optimized by orthogonal experiment. The inclusion method, the ratio of ginger oleoresin to β-cyclodextrin and inclusion time were studied as factors of inclusion process. RESULTS: The optimized extraction technology was as follows: extraction temperature was 50℃, extraction pressure was 25 MPa, separation pressure was 9 MPa and extraction time was 90 min. The optimal inclusion method was triturating inclusion, with the ratio of ginger oleoresin to β-cyclodextrin of 1:8 and inclusion time of 60 min. CONCLUSION: The optimized technology of extraction and inclusion is stable and feasible, and can be used for the extraction and inclusion of ginger oleoresin.
