Abstract : It was shown previously (Chem. and Ind., 1962, 743) that the major constituent (component V, 50.5%) of the oil of araucaria (wood oil of the New Caledonian conifer Neocallitropsis araucarioides (Compt.) Florin syn. Callitropsis araucarioides Compt.) is a mixture of alphaand beta-eudesmol and that component II (8%) is guaiol. Bates and Hendrickson (Chem. and Ind., 1962, 1759) have reported that component III (19.5%), from which a small amount of alpha-cadinol was isolated, was mainly gammaeudesmol. It has now been found that component I (2%) is elemol and that component VI (18%) consists mainly of a new sesquiterpene alcohol, for which the name 'araucariol' is proposed. The present finding of fairly large amounts of araucariol, which has a carbon skeleton different from that of the eudesmols, guaiol or elemol, as well as small amounts of cadalene precursors, indicate that in the oil of araucaria biogenesis of sesquiterpenes does not arise solely from transfarnesol.
