In order to determine the structure (IV or V) of l-phanostenine, the phenolic aporphine-type base contained in Stephania Sasakii HAYATA (Menispermaceae), dl-1, 2-methylenedioxy-9-hydroxy-10-methoxyaporphine (V), m. p. 111-113°, was synthesized and its ultraviolet and infrared absorption spectra were compared with those of the natural product. They were clearly different and showed that phanostenine does not take the structure represented by (V).
