| Abstract: | After optimizing the chromatographic conditions including column system,temperature program and modulation parameters,an analytical method of zedoary volatile oil was established based on comprehensive two-dimensional gas chromatography/time-of-flight mass spectrometry(GC×GC/TOFMS). The analysis of the individual components and groups were achieved. Under the optimized conditions the components of zedoary volatile oil from Guangxi province,China were identified by GC×GC/TOFMS. Among 249 components with similarities over 800,there are 18 terpenes,34 oxygenated terpenes,35 sesquiterpenes and 37 oxygenated sesquiterpenes. Sixty-nine of these components have the individual volume fractions of over 0.02%. |
