Abstract
The alkaloid composition of Datura innoxia plants was analysed by quartz capillary GLC and GLC-MS. Significant differences were
found in the alkaloid pattern of the respective plant organs even between different
aerial parts. More than 30 alkaloids could be identified. Besides previously known
substances, a further 18 tropine ester alkaloids as well as hygrine and tyramine were
identified. Seventeen of these alkaloids have not been formerly found in the genus
Datura. Additionally, two hitherto unknown hygrine derivatives, presumably isomeric N-methylpyrrolidinyl-hygrines, were characterized.
