Optimization of Extraction Process for Total Anthraquinones from Rheum spiciforme by Supercritical CO2 Method
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.
