Publisher's Synopsis
Excerpt from Year-Book of Pharmacy, Comprising Abstracts of Papers Relating to Pharmacy, Materia Medica, and Chemistry Contributed to British and Foreign Journals, 1893, Vol. 2
Recent contributions to the literature of solanaceous alkaloids do not remove the doubt cast on the existence of hyoscine, C17 h23n 03, as a distinct base. A. Ladenburg, while admitting the occurrence of scopolamine in commercial hyoscine, disputes the supposed identity of these two bodies on the strength of analytical results and crystallographic measurements. On the other hand, E. Schmidt repeats his assertion that the commercial hyoscine preparations examined by him, and supplied to him as salts of Ladenburg's hyoscine, not merely contain, but consist essentially of salts of scopolamine but he does not for the present deal with the question whether or not such a body as hyoscine of the formula C17 H23 N 03 may after all occur in henbane or other solanaceous plants. 0. Hesse, like E. Schmidt, finds the com position of hyoscine to correspond to the formula C17 H21 N 04, which exactly coincides with that of scopolamine. The identity of Hesse's atropamine with apoatropine is again asserted by E. Merck, who also reports the isolation of a new alkaloid, pseudohyoscyamine, from Duboisia myozwror'des.
