【Abstract】 An essential oil from Tolu concrete was isolated and its amount was measured by a volatile oil distillator. The components of the essential oil were analyzed by GC and GC-MS. 17 compounds of them were identified by GC-MS and quantified by GC with normalization method of peak areas. The method is simple and rapid, it is suitable for quality control and routine analysis of concrete flavouring.更多还原
