Sesquiterpenes (C15H24) and their corresponding oxygenates are common, but important constituents of most essential oils. They are one isoprene unit higher than monoterpenes and thus the possible structural permutations and combinations are considerably greater. Though many key sesquiterpenes such as beta-caryophyllene, germacrene D and delta-cadinene, have been structurally elucidated, many remain to be characterized. In addition they are difficult to synthesize or isolate and usually occur as complex mixtures. Thus their olfactive properties are also largely unreported. Though when reported, they are generally described as having a variety of woody aromas. The oxygenated sesquiterpenes are even less characterized or organoleptically described. This paper reviews key sesquiterpene compounds and where possible their reported tastes and aromas.
