| Description | A further alkaloid isolated from Vinca minor L., this base is possibly optically
inactive, the specific rotation reported being [α]D 00 ± 2° (c 1.0, EtOH). The
ultraviolet spectrum in EtOH has a broad absorption maximum at 338 mil and
an inflexion at 310 mil. The structure has been confirmed by the synthesis of the
(±)-form. | | References | Kokry, Dubravkova, Sefecovic.,Experientia, 18,564 (1962)
