  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.

  二水合薄荷内酯是猫薄荷(Nepeta spp.)精油中的一种次要成分，如猫草(Nepeta cataria)。已确定其为有效的驱虫化合物。可以通过对猫薄荷精油的主要成分薄荷内酯进行氢化来合成二水合薄荷内酯。这种化合物及其组合物也具有香味特性，可以商业上用于其驱虫特性。
