Abstract

Four species of the genus Vernonia, endemic in Cuba, have been investigated on the presence of sesquiterpenic lactones. In addition to two derivatives of lupeol, scopoletin, genkwanin and velutin, total 15 sesquiterpenic lactones have been isolated, four of which are described for the first time.
