GC-MS Analysis of Chemical Composition of the Essential Oil of Toona sinensis (A. Juss.) Roem Roots

摘要

The essential oil of Toonasinensis (A. Juss.) Roem roots, a traditional herbal medicine in China, was extracted by hydrodistillation and analyzed by gas chromatography coupled to mass spectrometry (GC-MS). Twenty compounds were identified. The essential oil yield and the percentage of identified compounds were 1.62 and 91.23 %. respectively. The major components were tridecane (15.54 %). tetradecane (7.00 %), 9-octadecenoic acid, methyl ester (6.19 %), 13-docosenoic acid, methyl ester (5.13 %), (Z,Z)-9,12-octadecadienoic acid (4.53 %), 1-hexadecyne (3.79 %), and α-cubebene (3.07 %). The study can provide quality control evidence and further exploitation of Toonasinensis (A. Juss.) Roem.
