Abstract
The method of calculating theoretical content of triacylglycerols with ECN42 in olive oil was introduced,which distinguished adulteration of olive oil by determination of the absolute difference be-tween actual and theoretical content of triacylglycerols with ECN42(△ECN42). The HPLC condition to quantify ECN42,and the reproducibility of the method was researched. The results showed that using dif-ferential refractometer as the detector,column temperature 38 ℃,mobile phase acetone / acetonitrile (50∶ 50,V/ V),flow rate 1. 5 mL/ min,under the condition,it showed a good chromatographic separation effect with good repeatability,and RSD less than 1% and S R between 0. 02 and 0. 11. It provided basis for instituting national standard.关键词
