I think scopolamine is the major chemical in datura above and beyond the atropine also present.

From Roger Gfeller's tox book: Datura is toxic in all parts, especially the seeds-the active toxins are atropin, hyoscyamine, and scopolamine.

What is of interest is atropine, scopolamine, even methyecgonine share the same base tropane, and differ only at the (?) ester bond.

The plants switch out the inorganic tail enzymatically while chemists have to use multiple steps to force the equation to the left.
