Analysis by gas chromatography–mass spectrometry of the volatile components of Teucrium lusitanicum and Teucrium algarbiensis

The essential oils from four samples of Teucrium lusitanicum and one sample of Teucrium algarbiensis, grown in Algarve (southern Portugal) were analyzed by gas chromatography (GC) and gas chromatography–mass spectroscopy (GC–MS). Seventy-one volatile compounds were identified. Major compounds of T....

Description
Summary:The essential oils from four samples of Teucrium lusitanicum and one sample of Teucrium algarbiensis, grown in Algarve (southern Portugal) were analyzed by gas chromatography (GC) and gas chromatography–mass spectroscopy (GC–MS). Seventy-one volatile compounds were identified. Major compounds of T. algarbiensis oil were α-pinene (8.3%), sabinene (7.2%), β-pinene (10.2%), limonene (11.8%) and germacrene D (7.6%). Concerning T. lusitanicum, some quantitative differences were found with regards to the major constituents of the oils from four populations: α-pinene (0.8–8.5%), sabinene (2.1–9.6%), β-pinene (2.5–11.9%), limonene (1.2–11.5%) and elemol (2.6–12.0%).
