Jasmone<\/strong>\u00a0is a natural\u00a0organic compound<\/a>\u00a0extracted from the volatile portion of the oil fromjasmine<\/a>\u00a0flowers. It is a colorless to pale yellow liquid that has the odor of jasmine. Jasmone can exist in two\u00a0isomeric<\/a>\u00a0forms 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.<\/p>\n

Jasmone is produced within plants by the metabolism of\u00a0jasmonate<\/a>, from\u00a0linolenic acid<\/a>\u00a0by the\u00a0octadecanoid pathway<\/a>. It can act as either an attractant or a repellent for various insects. Commercially jasmone is used primarily in perfumes and cosmetics.<\/p>\n
