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.

Key words: oil, BHA, BHT, TBHQ, PG, matrix solid-phase dispersion, HPLC
