Study on Extraction Technology of Conessine from Holarrhena antidysenteriaca
Abstract:Objective:The process of extracting conessine from Holarrhena antidysenteriaca optimized for establishing the quality control standards of Holarrhena antidysenteriaca.Methods: Based on the results of single factor tests,we selected extraction time,methanol concentration and solid/liquid ratio as the experimental factors and used the extraction yield of conessine from as the response value.Results:The optimal extraction parameters were as follows: extraction time 70 min,methanol concentration 75%,solid/liquid ratio 1:9.Conclusion:The extraction method is reliable,reasonable and highly predictable.
