| Abstract: | Different extraction methods of bioactive component squalene in rices were studied and a new method was developed for the determination of squalene in rices.The squalene in rices from different areas were extracted by Soxhlet extract method,and analyzed by gas chromatography-tandem mass spectrometry(GC-MS/MS).The results showed that the calibration curve was linear over the concentration of squalene in the range of 1-50 mg/L with a correlation coefficient of 0.998 7.The detection limit(LOD) was 0.1 mg/kg.Th... |
