METHOD FOR SEPARATING EPHEDRINE FROM EPHEDRA SINICA STAPF AT A HIGH YIELD, AND ADJUVANT FOR ENHANCING IMMUNITY CONTAINING EPHEDRINE AS AN ACTIVE INGREDIENT

摘要

The present invention relates to a method for isolating ephedrine from Ephedra sinica Stapf, which is a representative medicinal herb, at a high yield, and to an adjuvant for enhancing immunity containing the ephedrine as an active ingredient. The inventors of the present invention performed a process at an ultra-high pressure to efficiently obtain ephedrine from Ephedra sinica Stapf, and extracted ephedrine by using a solvent of sulfuric acid and ethyl alcohol mixed at a ratio determined through fractionation, without the conventional addition of diethyl ether.
