摘要: 采用基质固相分散萃取植物油中抗氧化剂叔丁基羟基茴香醚(BHA),叔丁基对羟基甲苯(BHT),特丁基对苯二酚(TBHQ)和没食子酸丙酯(PG),经高效液相色谱进行分离。回收率在85.8%~94.3%,相对标准偏差为2.1%~4.0%,最低检测限为2ng。

Abstract: An analytic method for simultaneous determination of BHA, BHT, TBHQ and PG in vegetable oil was developed by matrix solid phase dispersion (MSPD). The sample was separated with high-performance liquid chromatography. The recoveries range of determination is 85.8%~94.3%. The relative standard deviation (RSD) is 2.1%~4.0%. The detection limits are 2 ng.
