title: Volatile constituents of Stachys palaestina L. (Palestine woundwort) growing in Lebanon.
abstract: The hydrodistillation of the aerial parts of Stachys palaestina L. collected in Lebanon in the Kadisha Valley, yielded 0.1% (w/w) of essential oil. GC and GC-MS analyses enabled the identification of 87 compounds representing 90.8% of the total oil. Hexadecanoic acid (10%), hexahydrofarnesyl acetone (6.9%), eugenol (4.3%) and (E)-caryophyllene (4.3%) were the main components. On the whole, the oil was constituted mainly of sesquiterpenes (37.7%), among which sesquiterpene hydrocarbons (20.7%) slightly prevailed over oxygenated sesquiterpenes (17.0%). This is the first report on the chemical composition of S. palaestina essential oil.
