摘要
Four major food grade antioxidants, propyl gallate (PG), butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), and tertiary butylhydroquinone (TBHQ), were separated using micellar electrokinetic capillary chromatography (MEKC). The separation was completed with excellent resolution and efficiency within 6 min and picomole amounts of the antioxidants were detectable using UV absorption. In contrast, reversed-phase high-performance liquid chromatography separation was not as efficient and required larger sample amounts and longer separation time.
