A method for the determination of ephedrine in collunarium by high performance capillary electrophoresis with square wave amperometric detection(SWAD)was developed.
There are three very different orders, each with only one genus: Gnetales (Gnetum), Ephedrales (Ephedra or joint-firs), and Welwitschiales (Welwitschia).
In fact, it became popular because the standard over-the-counter decongestant, pseudoephedrine -the active ingredient in regular Sudafed-got locked up behind pharmacy counters.
