Tropane alkaloid

Tropane alkaloids, also known as Belladonna alkaloids are a class of alkaloids and secondary metabolites that contain a tropane ring in their chemical structure. Tropane alkaloids occur naturally in many members of the plant family Solanaceae.

Important tropane alkaloids are:

Anticholinergics
Anticholinergic drugs and deliriants:


 * Atropine, racemic hyoscyamine, from the deadly nightshade (Atropa belladonna)
 * Hyoscyamine, the levo-isomer of atropine, from henbane (Hyoscamus niger) and mandrake (Mandragora officinalis)
 * Scopolamine, from henbane and Datura species (Jimson weed)

Stimulants
Stimulants and cocaine-related alkaloids:


 * Cocaine, from Erythroxylum coca
 * Ecgonidine, and methylecgonidine, pyrolysis products of cocaine
 * Ecgonine, a precursor and metabolite of cocaine
 * Benzoylecgonine, a metabolite of cocaine
 * Cocaethylene, a metabolite of cocaine
 * Hydroxytropacocaine, from Erythroxylum coca
 * Methylecgonine cinnamate, from Erythroxylum coca

Others

 * Catuabines, found in the drug catuaba, from Erythroxylum vacciniifolium

Non-natural tropanes

 * Phenyltropanes
