| Abstract: | By using microwave-assisted extraction, the chemical components in ethanol extract from broccoli were analyzed by gas chromatography mass spectrometry （ GC-MS ） .The method is reliable, and can be used for researching the nutrition value and health function of broccoli.45kinds of individual components were identified by comparison of both mass spectra and GC retention time with those existing in the data system libraries.The relative abundances of the components were determined by normalization methods, showing that the 45kinds of components occupied 85.05% of total mass. |
