Analysis of the polar fraction of Haitian vetiver oil

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 1H- and 13C-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),...
