Jasmone is an organic compound, which is a volatile portion of the oil from jasmine flowers.

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.

Commercially, jasmone is used primarily in perfumes and cosmetics.
