摘要：

The six Ephedra alkaloids (ephedrine, norephedrine, pseudoephedrine, norpseudoephedrine, methylephedrine and methylpseudoephedrine) in 12 species of Chinese Ephedra collected in 16 districts of China were separated and identified by gas chromatography combined with mass spectrometry following trimethylsilylation of the extract. The alkaloidal concentrations were determined using a gas chromatograph equipped with a nitrogen phosphorus detector. The methods described are sensitive, accurate and simple to perform.
