Essential oils from Gomidesia schaueriana , G. sellowiana , G. spectabilis , G. anacardiifolia , G. palustris and G. tijucensis , collected in Southern Brazil, were analysed by GC and GC–MS. Fifty‐two compounds were identied, representing 92–98% of the oil contents. All samples were rich in cyclic sesquiterpenes (about 90%), mainly those from the cadinene and germacrene cyclization pathway. The oils from G. schaueriana , G. spectabilis , G. anacardiifolia and G. palustris were quite similar, with a predominance of β ‐caryophyllene, germacrene D, bicyclogermacrene, spathulenol, globulol and α ‐cadinol. G. sellowiana was rich in spathulenol, followed by geranylgeraniol, and G. tijucensis was characterized by the presence of α ‐ and β ‐selinene. Copyright © 2003 John Wiley & Sons, Ltd.
