| Abstract: | Two tangerine oil samples from different places of production were dissolved in hexane. The fatty acids of them were saponified and methylated in KOH-CH3OH solution, then separated in capillary DB _ WAX column and identified by GC-MS. Their relative contents were quantified by normalizing method of area. There are distinct differences of main fatty acid components between the two. The relative content of unsaturated acids in tangerine oil was 92.1% for the oil from Dachuan and 76.7% for the oil from Wanxian. |
