Summary
By separating the total alkaloids ofV.erecta according to their basicities in an APS, in addition to bases known previously we have isolated ervincidine, apovincamine, (+)-quebrachamine, dl-eburnamine, (−)-1,2-dehydroaspidospermidine, and kopsanone. This is the first time that these alkaloids have been obtained from this plant. Thin-layer chromatography showed the presence of another 10–12 uncharacterized alkaloids.
The region of the passage into the buffer solutions of some alkaloids has also been established.
