Mit Hilfe transgener Atropa belladonna-Pflanzen konnte die Ausbeute an Scopolamin im Vergleich zu natürlichen Pflanzen gesteigert werden. Verwendung Scopolamine, acting as an antagonist at both peripheral and central muscarinic receptors, is thought to be the primary compound responsible for the toxic effects of these plants. Tropane alkaloids are found in all parts of the plants, with the highest concentrations found in their roots and seeds. Fifteen different tropane alkaloids and derivatives were identified by GC-MS in various plant organs of Atropa baetica. The main root and leaves displayed the largest number of tropane alkaloids, most of which were also present in lateral roots. In contrast, only five of these alkaloids appeared in stem tissue. Quantitative analysis by HPLC showed the presence of the two major tropane ...

    Tropane alkaloid - Wikipedia

    Tropane alkaloids are a class of bicyclic.2.1] 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. Some tropane alkaloids have pharmacological properties and can act as anticholinergics or stimulants. Scopolamine, also known as hyoscine, is a tropane alkaloid drug with muscarinic antagonist effects.. It is obtained from plants of the family Solanaceae (nightshades), such as henbane or jimson weed (Datura species). It is among the secondary metabolites of these plants.. The drug can be highly toxic and should be used in minute doses.
