Determination of Four Synthetic Phenolic Antioxidants in Edible Oils by High-Performance Liquid Chromatography with Cloud Point Extraction Using Tergitol TMN-6

Simultaneous determination of six synthetic phenolic antioxidants in edible oils using dispersive liquid–liquid microextraction followed by high‐performance liquid chromatography with diode array detection

“…As a major source of lipids and micronutrients in the human diet, the QC of vegetable oils in the food industry is of great concern . Various analytical methods have been reported for determining SPAs in edible oils individually or simultaneously, including LC and HPLC , HPLC–MS , GC , GC–MS , voltammetry and MEKC . However, the reported methods usually suffer from large quantities of organic solvents in liquid solvent extraction or in the elution procedure of SPE, require a large amount of sample, and waste time.…”

Application of thermal ultrasound‐assisted liquid–liquid micro‐extraction coupled with HPLC‐UV for rapid determination of synthetic phenolic antioxidants in edible oils

“…Synthetic phenolic antioxidants (SPAs) are frequently used because of their availability, low cost, high efficiency, and stability (Amlashi et al, 2014;Xu et al, 2016). The most common SPAs, which are used alone or in combination, in oil are propyl gallate (PG), butylated hydroxyanisole (BHA), tert-butylhydroquinone (TBHQ), and butylated hydroxyltoluene (BHT) (Chen et al, 2013;Ding & Zou, 2012). Recent studies have shown that excessive intake of these antioxidants may be harmful to human health (Grice, 1986;Grice, 1988;Namiki, 1990;Okubo et al, 2003;Wilson & Bahna, 2005).…”

A novel fatty-acid-based in-tube dispersive liquid–liquid microextraction technique for the rapid determination of nonylphenol and 4-tert-octylphenol in aqueous samples using high-performance liquid chromatography–ultraviolet detection

“…When the temperature increases to a critical value, the mixed surfactant-sample solution is separated into two phases, one being the surfactant-rich phase containing the analytes and the other being the aqueous phase. CPE had the advantages of having a high enrichment and being a simple process [19][20][21][22][23]. Similarly, Yazdi and Es'haghi [24] introduced a surfactantenhanced LPME (liquid-phase microextraction) to extract basic drugs of abuse in hair using Triton X-100.…”
