ABSTRACT
Objective An effective method for separating coumarin from Artemisia capillaris by solvent sublation was established.Methods The effects of sublation solvent,the concentration of sample solution,N2 gas flow rate,pH value of solution,sublation time,and electrolyte NaCl etc.on the sublation efficiency were investigated and the optimal conditions of the solvent sublation were obtained.Results In the optimal conditions,the results of the solvent sublation were evaluated and compared with the solvent extraction.Conclusion The experimental results show that this method is simple and rapid,and the efficiency of coumarin by solvent sublation is far better than that by the solvent extraction.
