The structure of vinerine and vineridine

Summary 1. The epigeal part ofV. erecta gathered in the Tashkent Oblast in the early vegetation period contains a mixture of alkaloids (2.7%). Separation of the total alkaloids gave vincanine, vincanidine, vinervine, akuammine, kopsinine, pseudokopsinine, and the new bases vinerine and vineridine.2. The structure of vinerine has been established by a study of the IR, NMR, and mass spectra. Vineridine is isomeric with vinerine at C₃ and C₇.3. A new base, hydroxyindole reserpinine, has been obtained from reserpinine.Khimiya Prirodnykh Soedinenii, Vol. 2, No. 4, pp. 260–265, 1966
