• Beschreibung

  This yohimbine type alkaloid is a constituent of Rauwolfia vomitora and may be purified by recrystallization from MeOH when it forms colourless leaflets of the hemihydrate. It yields crystalline salts, e.g. the hydrochloride, m.p. 280-2°C and the tartrate, m.p. 215-6° C (dec.). The alkaloid is dextrorotatory with [α]_D + 32.5° (c 1.0, CHC13). The structure is that of 10-methoxyraunitidine.
