Abstract

The isolation of a number of indole, oxindole and glycosidic alkaloids from Vinoa major L. var. elegantissima Hart. was reported earlier from this laboratory. We now report the structure of two minor indole alkaloids designated as vincarpine (1) and dihydrovincarpine (2) isolated from the same plant.
