Among drugs of plant origin, alkaloids of the tropane group (atropine, hyoscyamine, scopolamine), isolated from plants of the Solanaceae family, are widely used in medical practice. The tropane alkaloids a- and jS-belladonnines are isolated from the plants Physoclaina alaica [1], Datura innoxia [2], and Datura stramonium [3].
