Description

A further alkaloid of this name has been described by Russian workers from Saussurea elegans M.B. Spreng. This base is dextrorotatory with a specific rotation of [α]D+ 75.4° (c 0.87, dimethylformamide). It forms a crystalline hydrobromide with m.p. 210°C and from the structure given and the published physical constants it is clearly not identical with that earlier described from Vinca elegantissima Hort.
