Chemical Constituents of Essential Oil and Hydrosol Extract from Teucrium kabylicum Batt., an Endemic Species from Algeria

The main objective of this study was to determine for the first time the chemical composition of the essential oil and hydrosol extract of Teucrium kabylicum Batt growing in south Algeria. In this study, the aerial parts of the plant were hydrodistilled in a Clevenger- type apparatus. The isolated essential oil and hydrosol extract were analyzed using gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS). The essential oil of T. kabylicum was principally characterized by monoterpene hydrocarbons compounds represented by limonene (23.5%) and terpinolene (19.5%), followed by aliphatic compounds represented by hexanol (26.5%). The major compounds of hydrosol extract were terpinene-4- ol (23.5%), limonene, 1-2-epoxide (15.6%), citronellal (13.6%), caryophyllene oxide (8.6%), geraniol (5.6%) and spathulenol (3.6%). The essential oil of T. kabylicum was principally characterized by monoterpene hydrocarbons and aliphatic compounds, while hydrosol extract was characterized by oxygenated components only
