Geographical Variation of Ajuga laxmannii (L.) Bentham Essential Oil

Abstract

Aerial parts of Ajuga laxmannii collected from five different localities in Turkey were hydrodistilled for 3 h using a Clevenger-type apparatus to produce a small amount of essential oil which was trapped in n-hexane. Oils were analysed by gas chromatography (GC) and mass spectrometry (GC/MS). The main components were as follows:  sample A: Nonacosane (17.8%), Heptacosane (12%), Hexahydrofarnesyl acetone (11.2%); sample B: Hexadecanoic acid (21.2%), Dodecanoic acid (12.3%), Tetradecanoic acid (8.9%); sample C: Phytol (12.5%), Hexadecanoic acid (10.0%), Hexahydrofarnesyl acetone (8.6%); sample D: Hexahydrofarnesyl acetone
(9.1%), Hexadecanoic acid (8.9%), Nonacosane (7.6%); sample E: Hexadecanoic acid (13.6%), Phytol (13.3%), Hexahydrofarnesyl acetone (8.3%).
