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.
