J. Planar Chromatogr. 30, 474-480 (2017). HPTLC of phenol (1), pyrocatechol (2), hydroquinone (3) and trihydroquinone (4) in urine samples on silica gel with hexane – dioxane – ethyl acetate 7:1:2. Detection by spraying with Folin‒Ciocalteau phenol reagent – water 1:2. Visible blue color zones of the four phenolic benzene metabolites were punched 2 cm in diameter individually using a paper punching machine, and collected in test tubes containing 1 mL of distilled water. To 10 μL of Folin–Ciocalteu reagent in each tube 60 μL of 20 % sodium carbonate solution were added. Quantitative determination by absorbance measurement at 765 nm. The hRF values for (1) to (4) were 69, 40, 28 and 9, respectively. Linearity was between 0.25 and 1.5 mg/mL for (1) to (4). LOD and LOQ were 9 and 3 μg/mL for (1), 30 and 90 μg/mL for (2), 6 and 18 μg/mL for (3), and 7 and 21 μg/mL for (4). The intermediate/interday/intra-day precisions were below 4 % (n=5). Average recovery was between 92 and 98 %.
