Behavioral Effects of Plant-Derived Essential Oils in the Geller Type Conflict Test in Mice

概要

The present study was conducted to further explore plant−derived essential oils that possess an anticonflict effect using the Geller type conflict test in ICR mice.The benzodiazepine anxiolytic diazepam increased the response(lever pressing)rate during the alarm period(i.e., an anticonflict effect), but the 5−HT1A partial agonist buspirone did not.Oils of juniper, cypress, geranium and jasmine did not produce any effect in this test.Frankincense oil decreased the response rate during the safe period at 1600 mg/kg, but did not exhibit any effect on the response rate during the alarm period.In contrast, lavender oil increased the response rate during the alarm period in a dose−dependent manner in the same manner as diazepam.These results indicate that not only rose oil but also lavender oil possess an anticonflict effect in mice.
