Certain active cytotoxic alkaloid fractions prepared from Catharanthus trichophyllus roots were investigated. This work resulted in the isolation of ajmalicine, pericalline, tetrahydroalstonine, vindolinine, and ursolic acid. These compounds were not responsible for the observed cytotoxic activity.
## Abstract 17βdesacetoxyvinblastine and 17βdesacetoxyleurosine have been isolated from Catharanthus roseus. The latter has not been recognized so far in this plant. The ^1^H NMR and mass spectrometry data confirming the proposed structures are presented.
