Abstract
|
|
|
|
The aerial parts of Ephedra aphylla afforded two alkaloids belonging to two different classes. The first alkaloid, ephedradine C, belonging to the spermine alkaloid, a group characterized by its hypotensive effect. The other alkaloid, hordenine is a phenylalkylamine alkaloid isolated for the first time from Ephedra Species. The structures were elucidated by spectroscopic methods and the assignment of some carbons in ephedradine C was achieved based on 2 D-NMR experiments.
