From the epigeal part ofVinca erecta growing in the village of Sagyrdasht, Tajik SSR, we have isolated vincamine, vincanine, vinervinine, ervamine, akuammicine, vincanidine, akuammine, and a new base C20H22N2O3 with mp 228–229°C, [α] D 30 + 71° (c 0.7; methanol).
On the basis of IR, UV, NMR, and mass spectra on chemical properties, the structure of 11-hydroxypleiocarpamine has been proposed for the new compound.
