Chemical examination of Eupatorium trapezoideum has furnished five cadinenes 1a, 2a, 2b, 4a and 5 and a degraded cadinene 3a whose stereostructures are presented in this paper.The absolute stereochemistry of the major component 1a has been determined by application of Horeau's method as well as chemical correlation studies and has been confirmed by X-ray analysis of 1f thus suggesting that it belongs to the amorphane group.
