“…7). 3 The parent ion of the amphetamine byproduct {m/z 136 (M À 1)}, is 14 mass units (a methylene group) lower than that observed for CMP, thus indicating the CMP analogue 1-(1 0 ,4 0 -cyclohexadienyl)-aminopropane (CAP). Conversely the parent ion in the N,N-dimethylamphetamine byproduct {m/z 164 (M À 1)}, is 14 mass units higher, indicating the CMP analogue 1-(1 0 ,4 0 -cyclohexadienyl)-2,2-dimethylaminopropane (CDP).…”

Although the traditional use of Ephedra 'ma huang' has been established for thousands of years, its resurgence in the US as a herbal dietary supplement is currently a matter of national controversy. At the heart of the debate are three important questions: (1) the identity and composition of Ephedra products with regard to ephedrine and related alkaloids; (2) the potential therapeutic utility of Ephedra supplements for weight loss or performance enhancement; and (3) potential health risks associated with such uses of Ephedra, particularly in sensitive individuals or in cases of intentional abuse for its stimulant properties. This review surveys the literature on Ephedra with regard to traditional uses, botany, chemistry, analytics, pharmacological effects and health risks. A brief discussion of the central issues in the current debate on the regulation of Ephedra in the United States is included as this is where most of the problems have occurred to date.

“…Representative and known to cause adverse effects on the digestive system is E. viridis Coville. However, species in North America, in spite of their purported medicinal use as teas, contain no detectable amounts of these alkaloids (Nielsen et al 1927;Terry 1927;Nielsen and McCausland 1928;Reti 1953). Their stems are jointed and bear whorled, fascicled, or opposite, terete, photosynthetic branches.…”
