 +Red cedarwood oil possesses a soft, pleasant, balsamic typical cedarwood odor. Fractionation and analysis of Virginia cedarwood oil made clear that hydrocarbons (thujopsene, cedrene) and cedrol (week woody odor) hardly contribute to the specific odor of the oil. Fractions with woody, amber, phenolic, lactonic, and grapefruit aspects were found. Oxygenated sesquiterpenes like betulenal (with odor aspects of sandalwood and acetylcedrene), funebrenal (8-cedren-15-al or α-cedrenal, woody), thujopsenal, chamigrenal, 8-cedren-10-one (musty, woody, mint, myrrh-like), and nootkatone (grapefruit-like) seem to contribute to the typical cedarwood character of the oil. \\
