Chemical Composition of the Essential Oils Extracted from the Leaf and Flowers of Nepeta haussknechtii Bornm. in Iran.

The volatile constituents of the oil extracted from the leaves and flowers ofNepeta haussknechtiiBornm. were isolated through a hydrodistillation method and then analyzed by GC and GC-MS. The identified components accounted for 98.9%, 99%, of the leaves and flowers, The leaf oil was found to contain 26 components and the flower oil contained 25. The major constituents of the leaf oil were germacrene D (32%), and caryophyllene oxide (16.5%), and the main components of the flower oil were germacrene D (41.5%),, E-caryophyllene (20.2%) and thymol (7.7%).
