Hyoscyamal, a new tetrahydrofurano lignan from Hyoscyamus niger Linn.
In addition to the isolation and complete characterisation of a new lignan, hyoscyamal, three other compounds, balanophonin, pongamoside C and pongamoside D have been isolated from the seeds of Hyoscyamus niger. The structures of the compounds were settled on the basis of spectroscopic analysis. This is the first report on the isolation of these compounds from a solanaceous plant.
