Abedi, Abdol-Samad published the artcileApplication of thermal ultrasound-assisted liquid-liquid micro-extraction coupled with HPLC-UV for rapid determination of synthetic phenolic antioxidants in edible oils, Application In Synthesis of 121-79-9, the publication is Journal of the American Oil Chemists’ Society (2021), 98(10), 969-978, database is CAplus.
A simple, fast, and reliable liquid-liquid micro-extraction (LLME) method assisted by thermal ultrasound approach was developed for simultaneous determination of synthetic phenolic antioxidants (SPAs) in edible oils by high-performance liquid chromatog. equipped with UV detector (HPLC-UV). The synthetic antioxidants were Pr gallate (PG), butylated hydroxyanisole (BHA), tert-butylhydroquinone (TBHQ), and butylated hydroxyltoluene (BHT). The best extraction conditions were observed were methanol/acetonitrile (1:1, volume/volume) as the solvent, ultrasound at 4 min, and a temperature of 40°C. The linearity of the calibration curves for the optimum conditions were R2 > 0.989 for all of the SPAs in a range from 1-200μ g ml-1. Relative standard deviation (RSD%) for five anal. was in range of 2.83% to 4.21%. Limit of detection (LOD) and limit of quantification (LOQ) were obtained in range of 0.012-0.06 and 0.04-0.2μ g g-1, resp. With regard to recovery, a range of 91%-116% was calculated for the spiked edible oils.
