Eleven known indole alkaloids: vallesine, aspidospermine, 11-methoxydi
chotine, apparicine, tubotaiwine, vincadifformine, condylocarpine, (-)
-rhazinilam, aspidospermatine, haplocidine, and 18-oxohaplocidine, hav
e been isolated from leaves and stems of Vallesia glabra (Cav.) Link.
(Apocynaceae) from Bolivia. Analysis of 2 D NMR spectra complete previ
