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

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

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%).
