title: [GC-MS analysis of volatile constituents from five different kinds of Chinese eaglewood].
abstract: Volatile oils of five different kinds of Chinese eaglewood were extracted with aether at room temperature. The chemical constituents and relative contents of the volatile oils were analysed by GC-MS. It showed that all the five volatile oils were mainly composed of sesquiterpenes, aromatic constituents and fatty acids. Several sesquiterpenes, such as hinesol, nootkatone, valerenic acid, velleral, guaiol, gamma-gurjunene, gamma-selinene, viridiflorol, isoaromadendrene epoxide, valencene, alpha-costol et. al., together with several aromatic constituents, 2,4-di-tert-butylphenol,4-methyl-2,6-di-tert-butylphenol, phenylpropionic acid, 1-(benzyloxy)-8-naphthol, anisylacetone, et. al. were found in the volatile oils of Chinese eaglewood for the first time. The samilarities and differences of the volatile oils from the five kinds of Chinese eaglewood were compared. It suggested that the quality of Chinese eaglewood could be evaluated by GC-MS analyse of the volatile oil.
