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.

生产方法
茉莉酮是茉莉油、黄水仙油、橙花油等精油的成分。工业合成可有多种方法,如用3-已烯醇为原料。如以甲基乙烯基酮为原料,与溴化氢加成得至2-溴乙基甲酮制成环状缩酮,在二羟基酸溶液中用乙炔的金属化合物缩合,生成乙炔缩酮。再与顺式2-戊烯-1-醇的对甲苯磺酸盐反应,将生成物用过氯酸处理成顺式8-(+)-烯-5-炔-2-酮,再经加氢制成2,4-二酮。将2,4-二酮在稀碱水溶液中进行分子内缩合而得到顺式茉莉酮。另一种制法是将γ-酮醛环化,然后再引入甲基而制得茉莉酮。 顺茉莉酮是很有价值的香料之
