Hernandulcin , a natural sweetener from the Aztec sweet herb Lippia dulcis , which is about a thousand times sweeter than sucrose, is derived from bisabolene .

Extraction

β-Bisabolen can of course be obtained from bergamot oil from Citrus bergamia. It can be obtained synthetically from farnesol (or nerolidol ) by the action of formate with elimination of water .
