Hyoscyamine

Tropane alkaloid

Hyoscyamine is a naturally occurring tropane alkaloid and plant toxin. It is a secondary metabolite found in certain plants of the family Solanaceae, including henbane, mandrake, angel's trumpets, jimsonweed, the sorcerers' tree, and Atropa belladonna. It is the levorotary isomer of atropine and thus sometimes known as levo-atropine.
