| Summary: | The essential oil of A. galanga, a common spice in Malaysia, was prepared from fresh and dried rhizomes and
analysed by means of capillary GC and GC/MS. Forty components were identified (only three of which were previously reported), accounting for 83-93 % of the oil, depending on its method of preparation. Apart from monoterpenes, monoterpene alcohols and esters, and sesquiterpenes, also methyleugenol, eugenol acetate, chavicol(4-allylphenol) and chavicol acetate were present. This is the first time the latter substance has been reported in nature. Standardization of GC is proposed and tentatively applied towards a more systematic use of the Kovats indices as an aid in the identification of the constituents of essential oils. |
