Abstract
Aerial parts of Vernonia fruticulosa furnished a large amount of glauc olide B, two known and one new cadinanolide as well as three known fla vonoids. The silica gel catalysed rearrangement of glaucolide B to one of the cadinanolides supports the proposal that cadinanolides isolate d from Vernoniinae may be artefacts derived from glaucolide type precu rsors. Aerial parts of Vernonanthura discolor afforded friedelanol, fr iedelin and beta-sitosterol. Copyright (C) 1997 Elsevier Science Ltd.
