Reinvestigations by Hartmann et al. (1986) showed a total of 13 alkaloids, mostly from the roots. The alkaloid pattern of root cultures was almost identical with the pattern of roots from the intact plant. Scopolamine, which is synthesized in the roots only, was detected in the medium. Cell suspensions of this species are able to produce small amounts of norhyoscyamine and 6-hydroxyhyoscyamine, but not scopolamine when fed with hyoscyamine (Hartmann et al. 1986). Interestingly, cell suspensions produced trace amounts of3-acetoxytropane and 3-tigloyloxytropane, which were not found in the intact plant.
