| Résumé : | During agronomical and chemical studies with Croton cajucara Benth. (Euphorbiaceae), a shrub native to the Amazon area possessing an essential oil rich in linalool, it was observed that some individuals of a germplasm bank produced an oil containing a hydroxylated sesquiterpene as major component (up to 44.3%). Originally misidentified as 5-hydroxycalamenene, the compound was further isolated and properly identified by 1H and 13C NMR as cis-7-hydroxycalamenene. Measured retention indices were 1759 (Ultra-1), 1804 (HP-5), 2212 (FFAP) and 2663 (Carbowax 20M). |
