Abstract

In this report, essential oils from the rhizome, stem and leaf of Etlingera brevilabrum were isolated using a Clevenger-type apparatus and subsequently characterized using a comprehensive two-dimensional gas chromatography (GC×GC/TOFMS) approach. Regarding the spectral assignments, 77 constituents were totally identified. The rhizome oil contained oxygenated monoterpenes (26.4%) and monoterpene hydrocarbons (25.9%), while the total percentages of these groups in the stem oil were found to be 27.5% and 25.2%, respectively. The leaf oil dominated by monoterpene hydrocarbons (32.4%) and oxygenated monoterpenes (27.3%). The major characterized compounds for the rhizome oil were 1,8-cineole (10.8%) and β-phellandrene (8.8%). The stem oil was mainly composed of 1,8-cineole (12.0%) and β-pinene (8.5%). However, monoterpene hydrocarbons involving β-pinene and α-pinene (8.7% and 5.5%) were identified as the main components in the leaf oil profile.
