Answer:
how do you extract ephedrine out of almond extract
Almond oil doesn't yield ephedrine, but synthetic bitter almond oil yields Benzaldehyde which can be fermented to give l-PAC (l-Phenylacetyl carbinol) which can be reduced with Al foil & mercury chloride (Al/Hg amalgam) to get l-ephedrine (l is the active isomer of ephedrine, it reduces to d-DMPEA)
