专利号:US-9314021-B2 优先权日:2004-11-03 标题 :Formulations containing insect repellent compounds 发明人:SCIALDONE MARK A 权利人:DU PONT 摘要:Dihydronepetalactone, a minor natural constituent of the essential oil of catmints ( Nepeta spp.) such as Nepeta cataria , has been identified as an effective insect repellent compound. Synthesis of dihydronepetalactone may be achieved by hydrogenation of nepetalactone, the major constituent of catmint essential oils. This compound, and compositions thereof, which also has fragrance properties, may be used commercially for its insect repellent properties.
