Atropine and hyoscine are used, to a large extent, in ophthalmic practice, to dilate the pupil of the eye (Trease and Evans, 1978).
D. stramonium L. contains from 0.2 to 0.45% alkaloids, the chief of which are hyoscyamine and hyoscine.
The roots contain, in addition to hyoscine and hyoscyamine, digitoyl esters of 3, 6 - dihydroxyatropane and 3, 6, 7 - trihydroxytropane, respectively and alkylamines
