| Abstract: | Objective: To optimize extraction process conditions of total anthraquinones from Rheum spiciforme by supercritical CO2.Method:With extraction pressure,extraction temperature and extraction time as factors,the content of total anthraquinones from extract of R.spiciforme as index,the content of total anthraquinones was determined by UV-visible spectrophotometry,technology conditions were optimized by orthogonal test.Result:Optimum technology conditions were as follows:extraction pressure was 25 MPa,extraction temperature was 50 ℃,extracted 2.0 h.The content of total anthraquinones in extract was 23.4 mg·g-1,transfer rate was up to 91.4%.Conclusion:This process was stable and feasible,it could be used to extracting total anthraquinones from R.spiciforme. |
