Abstract
In the previous paper the separation analysis of antioxidants by thin-layer chromatography was reported. The present report deals with the gas chromatographic analysis of BHA and BHT. Separation and simultaneous determination of BHA and BHT were investigated by using commercial thermo 1-1 (Shimadzu) as a stationary liquid and methyl caprate as a internal standard. Average recovery rates of BHA and BHT from edible oil were 98.4 and 92.9 per cent, and the standard deviations were 1.9 and 1.2 per cent respectively.
