What is Raubasine?
Description
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.

Definition
ChEBI: Ajmalicine is a monoterpenoid indole alkaloid with formula C21H24N2O3, isolated from several Rauvolfia and Catharanthus species. It is a selective alpha1-adrenoceptor antagonist used for the treatment of high blood pressure. It has a role as an antihypertensive agent, an alpha-adrenergic antagonist and a vasodilator agent. It is a monoterpenoid indole alkaloid, a methyl ester and an organic heteropentacyclic compound. It is a conjugate base of an ajmalicine(1+).
Purification Methods
It crystallises from MeOH, EtOH or EtOAc. [Beilstein 27 III/IV 7927.]
