Fatal Datura poisoning: identification of atropine and scopolamine by high performance liquid chromatography/photodiode array/mass spectrometry.
A forensic method comprising solid phase extraction and HPLC analysis was developed for the detection and confirmation of atropine and scopolamine, the main toxic alkaloids of Datura stramonium and Datura ferox. This method allowed the direct coupling of an electrospray (ZMD) mass selective detector to the HPLC system. Under these conditions, atropine and scopolamine were well separated from ot...

متن کاملEffect of Culture Medium on Hyoscyamine Production from Four Datura Sp Hairy Roots
Tropane alkaloids present a great economic value in particular for pharmaceutical industry. The culture of Datura sp hairy roots obtained by inoculation with A4 Agrobacterium rhizogenes offers promising prospects for alkaloids in-vitro production. The objective of our study is to try optimizing hyoscyamine production exploiting the composition of mineral fraction of the culture media. On the wh...
