Jasmone is an organic compound, which is a volatile portion of the oil from jasmine flowers. It is a colorless to pale yellow liquid. Jasmone can exist in two isomeric forms with differing geometry around the pentenyl double bond, cis-jasmone and trans-jasmone. The natural extract contains only the cis form, while synthetic material is often a mixture of both, with the cis form predominating. Both forms have similar odors and chemical properties. Its structure was deduced by Lavoslav Ružička.[1]
Jasmone is produced by some plants by the metabolism of jasmonic acid, via a decarboxylation.[2] It can act as either an attractant or a repellent for various insects. Commercially, jasmone is used primarily in perfumes and cosmetics.
