title: Gas-liquid chromatography-mass spectrometry investigation of tropane alkaloids in Hyoscyamus albus L. from Morocco.
abstract: Thirty-four alkaloids were identified in the organs of Hyoscyamus albus L. by gas-liquid chromatography-mass spectrometry (GLC-MS). Eight new compounds for the roots, eleven for the stems, twelve for the leaves, nineteen for the flowers, and seven for the seeds were detected. The alkaloids 5-(2-oxopropyl)-hygrine (8) and phygrine (20) are new for this species and 3-(hydroxyacetoxy)tropane (9), 6,7-dehydro-3-phenylacetoxytropane (15), 3-(2'-phenylpropionyloxy)tropane (17), 6,7-dehydro-3-apotropoyloxytropane (18), 3-(3'-methoxytropoyloxy)tropane (23), and aponorscopolamine (25) are described for the first time for the genus Hyoscyamus. Hyoscyamine was the main alkaloid in the plant organs.
