Chemical Composition of Essential Oils From the Pseudostem and Leaves of Meistera tomrey Growing in Vietnam

Abstract

Meistera tomrey, Zingiberaceae is a species native to Indochina. The present study reports the chemical compositions of essential oils extracted from the pseudostem and leaves of M tomrey. The results of the gas chromatography-mass spectrometry (GC/MS) analysis revealed varying compositions of specific compounds in both the pseudostem and leaves. In the pseudostem, β-pinene accounted for 14.2% and 1,8-cineole for 13.5%. As for the leaves, β-pinene comprised 6.6% and 1,8-cineole 16.7%. α-Pinene represented 6.9% in the pseudostem and 4.6% in the leaves, while borneol contributed 4.6% in the pseudostem and 4.2% in the leaves. Additionally, ( E)-caryophyllene constituted 3.6% in the pseudostem and 4.4% in the leaves, and ( E)-nerolidol 3.5% in the pseudostem and 7.6% in the leaves. This is the first report on the chemical compositions of essential oil from M tomrey.
