 Title    Determination of Hyoscyamine and Scopolamine in Datura innoxia Plants by High Performance Liquid Chromatography  
 Abstract    For the determination of the hyoscyamine-scopolamine content in small quantities of fresh plant tissue an HPLC assay was developed; with a sensitivity of about 20 ng alkaloid per run. Analysis of the different organs of Datura innoxia plants are in accord with the concept that hyoscyamine is synthesized in the roots, whereas transformation to scopolamine starts in these organs and proceeds in the aerial parts of the plant.

 Abstract    A ssem El-Shazlya c, A n d reas Teic, L udger W itteb, M äher E l-D om iatya and M ichael W inkc a D epartm ent The alkaloid composition of H yoscyam us boveanus, H. desertorum, H. muticus and H. albus was investigated by capillary GLC and GLC-mass spectrometry. Altogether 39 alka­ loids of the tropane and pyrrolidine types were identified. Several alkaloids were found in the different species for the first time, e.g., 22 alkaloids in H. boveanus, 13 in H. desertorum, 24 in H. muticus and 4 in H. albus. 3ß-Hyoscyamine, dehydrohyoscyamine, phyllalbine, 3a-phenylacetyltropane, phenylacetylscopine as well as phygrine and 2,3-diacetonyl-N-methyl-pyrrolidine are apparently new for the genus Hyoscyamus. Alkaloid profiles and alkaloid contents of flowers, fruits, leaves, stems and roots were determined and their chemoecological functions discussed.
