jasmone

= ** Jasmone ** =

====Jasmone is a natural [|organic compound] extracted from the volatile portion of the oil from [|jasmine] flowers. It is a colorless to pale yellow liquid that has the odor of jasmine. 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 containing both forms, with the cis form predominating. Both forms have similar odors and chemical properties.==== ====Jasmone is produced within plants by the metabolism of [|jasmonate], from [|linolenic acid] by the [|octadecanoid pathway]. It can act as either an attractant or a repellent for various insects. Commercially jasmone is used primarily in perfumes and cosmetics====

 **:** a liquid ketone C11H16O that is derived from cyclopentene, has an odor like that of [|jasmine], is found esp. in jasmine oil, and is used in perfumery

**Refractive Index:** 1.4990 Jasmone is a plant hormone which also repels or attracts various insects. It is frequently extracted from the jasmine plant, and it has the characteristic smell of jasmine. As a result of this property, jasmone is often used in perfumes and other products, as humans also tend to find the odor attractive. ||  ||
