Objective: To optimize preparation technology of coumarin from Angelica dahurica phospholipid complex. Method: With recombination rate as index
feeding ratio
the concentration of coumarin from A.dahurica
reaction time and temperature were selected as factors
preparation technology of coumarin from A.dahurica phospholipid complex was optimized by four factors quadratic regression orthogonal rotation combination design method. Result: Optimum preparation technology was as following:with tetrahydrofyran as reaction solvent
proportion of coumarin from A.dahurica to phospholipid 1:3
the concentration of coumarin 2 g·L-1
reaction temperature 50 ℃
reaction time 101 min.Recombination rate of the complex was up to 98.58%. Conclusion: This optimized preparation technology was stable and feasible
it could provide reference for further study on new preparations of coumarin from A.dahurica.
