How do you extract ephedrine from sida cordifolia?
ephedra is a shrub nativ to china that yealds L&DL-ephedrine how is it sxtracted? Powderize the ephedra, make it basic with NaOH and then steam distill it over. Neutralize the distillate with HCl acid, then use a rotovap (or hair dryer) to evaporate the water. Also, I'm pretty sure that Ephedra only yields the active isomers, that's l-ephedrine and D-pseudo. Plants of the genus "Sida" (S cordifolia, S rhombifolia etc) also yield Ephedrines. Do an A/B on Sida cordifolia extract ;^)
