What is Analysis of alkaloids in Chinese Ephedra species by gas chromatographic methods about?

## Abstract 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.
