Abstract
The alkaloid platyphylline, which is a valuable and difficultly available drug, is obtained from the above-ground portion of flat-leaved groundsel in which platyphylline (I) is accompanied by the alkaloid seneciphylline (II), which has limited application in medicine at the present time. The quantitative ratio of the contents of (I) and (II) in raw material is variable and oscillates within wide limits depending on many natural factors.
