Gaertn, an efficient and low-cost analytical method has been applied. For this purpose, a dispersive liquid\u2013liquid microextraction (DLLME) method, followed by UV-Vis spectrophotometric detection, was used. To form a cloudy solution, a binary mixture containing ethanol as a disperser solvent and chloroform as an extraction solvent was rapidly injected by syringe into a sample solution containing p-CA. After centrifugation, dilution of the obtained organic phase was done with the proper amount of ethanol, and the phase was transferred into a micro cell for subsequent measurement. Some effective parameters for the DLLME method, such as the volume of disperser solvent and extraction solvent, pH, and salt concentration were inspected by a 24 full factorial central composite design using design Export Software. Under the optimized conditions, linearity was between 10 and 150 ng\/mL, and the LOD was 2.3 ng\/mL. The results of the proposed method were similar to the obtained results using a GC with flame-ionization detection method.<\/jats:p>","DOI":"10.5740\/jaoacint.17-0189","type":"journal-article","created":{"date-parts":[[2017,8,15]],"date-time":"2017-08-15T01:15:05Z","timestamp":1502759705000},"page":"490-497","source":"Crossref","is-referenced-by-count":1,"title":["Extraction and Determination of Trace Amounts of p-Coumaric Acid in Vinegar, Carrot Juice, and Seed Extract from Silybum marianum (L.)
