Description and Uses
Vinca rosea L. yields this alkaloid which crystallizes as colourless needles from MeOH. The base is laevorotatory having a specific rotation of [α]D_620 (MeOH) and forms a crystalline hydrochloride, m.p. 281-3°e. The structure given above has been elucidated from chemical and spectroscopic data.
Antihypertensive, anti-ischemic.
