Abstract
The sesquiterpene lactone glaucolide B was isolated from the molluscicidal extract of Vernonia eremophila Mart, and shown to be responsible for the molluscicidal activity. Hydrogenolysis of glaucolide B resulted in the disappearance of the activity. Other inactive constituents of the extract were 3,7-dimethoxy-5,3′,4′-trihydroxyflavone and two transformation products, possibly artefacts, of glaucolide B. Glaucolide B exhibited strong antimicrobial activity against B, cereus and moderate activity against S. aurens, but was inactive in several other systems.
