A Rapid and Feasible (1)H-NMR Quantification Method of Ephedrine Alkaloids in Ephedra Herbal Preparations

A highly specific and sensitive proton nuclear magnetic resonance ((1)H-NMR) method has been developed for the quantification of ephedrine alkaloid derivatives in Ephedra herbal commercial prescriptions. At the region of δ 4.0 to 5.0 ppm in the (1)H NMR spectrum, the characteristic signals are separ...
