The polar part of commercial Haitian vetiver oil was converted to the methyl ethers, and this product separated by distillation and repeated flash chromatography (FC). The following new ( nor ‐) sesquiterpene alcohols were isolated as their methyl ethers and identified by their 1 H‐ and 13 C‐NMR spectra: 12‐ nor ‐ziza‐6(13)‐en‐2β‐ ( 2 ) and ‐2α‐ol ( 3 ), eudesma‐4(15),7‐dien‐3β‐ ( 7 ) and ‐2β‐ol ( 18 ), eudesma‐3,5‐dien‐1α‐ol ( 26 ), eremophila‐1(10),4(15)‐dien‐2α‐ol ( 31 ), eremophila‐1(10),11‐dien‐2α‐ol (nootkatol, 38 ), guaia‐1(5),11‐dien‐3‐ol ( 11 ), spirovetiva‐3,7(11)‐dien‐12‐ol ( 42 ), preziza‐7(15)‐en‐3α‐ol ( 14 ) and helifol‐1‐en‐14‐ol (syn. khusien‐14‐ol, 12 ). Furthermore, the hemi‐acetal 7,10‐epoxy‐salvialan‐10‐ol ( 8 ) was identified. The structure of some artefacts formed by alkylation of β‐vetivone 52 (→ M 39 , M 43 ) and of 11,12,13‐tri‐ nor ‐eudesmenone (→ 16 , 17 ) was also elucidated. Copyright © 2000 John Wiley & Sons, Ltd.
