Plant materials wsa air-dried in the shade prior to isolation of their oil.Leaf (120 g) was subjected to 3 h of hydrodistillation in a Clevenger-type apparatus. The resulting oil (yield: 1.1%, v/w, from leaf, respectively) was dried over anhydrous sodium sulfate and immediately placed into a dark glass tube and sealed. The essential oil from the leaf of Nepeta persica Boiss, analyzed by GC/MS analysis allowed identification of 19 components, which made up 93.46% of the total oil from the leaf part of plant , were shown to contain 4aα,7α, 7aβ-nepetalactone (49.46 %, respectively), 4aα,7α, 7aα-nepetalactone (14.18 % , respectively) and octane (13.10% , respectively).
