Occurs in peppermint oil, green tea and bergamot oranges (Citrus bergamia) 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. (Wikipedia)
