Determination of tert-butylhydroquinone content in vegetable oil by silica gel solid phase extraction-high performance liquid chromatography
A silica gel solid phase of the neutral alumina extraction-high performance liquid chromatographic method was established for the analysis of Tert-Butylhydroquinone (Tert-Butylhydroquinone,TBHQ) in the Vegetable oil.The amount of silica gel,oil,the polarity of the eluent,the velocity and the specifications of chromatography column were optimized in this experiment.The recovery rate and precision test experiments showed that:the recovery rate for 3.1 μg、5.4 μgand 13.6 μg were 95.6％-103.7％,RSD ％ were 3.5％-5.1％.The results of TBHQ content in the same sample were basically the same as that of NY/T1602-2008.This indicates that the method has good a accuracy and repeatability.It can be used for the determination of TBHQ content in vegetable oil.
