ABSTRACT
Background: A comparative analysis by using static headspace (HS) and steam distillation (SD) GC-MS of the volatile and the semi-volatile secondary metabolites from leaves of cultivated Majorana syriaca. Methods: The essential oils endogenous to cultivated thyme were isolated and identified by HS-GC-MS technology and compared to those from SD-GC-MS. Results: The HS-GC-MS results showed that the Palestinian cultivated thyme is rich in monoterpene hydrocarbons and phenolic monoterpenes such as α-phellandrene, α-pinene, β-myrcene, m-cymene, p-cymene, γ-terpinene, thymol and carvacrol. In all the samples γ-terpinene, p-cymene, thymol and carvacrol were the most abundant compounds. Conclusions: HS and SD-GC-MS have proved that most of the cultivated thyme samples examined has thymol isomer as the major phenolic constituent.
