Quantitative monitoring of the volatiles from the aerial parts of Satureja hortensis by the use of HS-SPME-GC-MS approach

Abstract

The volatile fractions isolated from the ground aerial parts of Satureja hortensis were trapped using the headspace solid phase microextraction (HS-SPME) strategy and subsequently monitored using gas chromatography in combination with mass spectrometry (GC-MS) instrumentation. Eleven constituents were totally recognized in the analyzed volatile parts, representing entire of the corresponding profile. Among the natural groups present in the chemical profile, monoterpene hydrocarbons (99.5%) were found as the major constituents with the dominant compounds being γ-terpinene (46.0%), p-cymene (11.8%), α-terpinene (11.1%), α-pinene (10.4%) and α-thujene (6.8%). However, lower contents of some natural compounds including myrcene (5.2%), β-pinene (3.9%), o-cymene (2.6%), α-phellandrene (1.1%), camphene (0.6%) and thymol (0.5%) were identified. Accordingly, only 0.5% of the profile included oxygenated monoterpenes.
