В пробирку вносят 0.1 мл препарата, упаривают на водяной бане досуха, прибавляют 0.01 г резорцина и 0.1 мл кислоты серной концентрированной и осторожно нагревают над пламенем горелки до тех пор, пока смесь не окрасится в темно-коричневый цвет. После охлаждения прибавляют 0.5 мл воды, затем 10% раствор натрия гидроксида до щелочной реакции (по посинению лакмусовой бумаги), после чего доводят объем раствора до 20 мл водой. Полученный раствор должен иметь оранжевую окраску с интенсивной зеленой флуоресценцией.

In tube making 0.1 ml of the drug uparivaût in a water bath, dry, add 0.01 g resorcinol and 0.1 ml of concentrated sulfuric acid and gently heated over a burner flame until mixture will turn dark brown. After cooling, add 0.5 ml of water, then 10% solution of sodium hydroxide to alkaline reaction (posineniû test paper), then bring the volume of solution to 20 ml with water. The resulting solution should be orange coloring with intense green fluorescence.

The tube was introduced 0.1 ml of the preparation were evaporated to dryness on a water bath, was added 0.01 g of resorcinol and 0.1 mL of concentrated sulfuric acid and carefully heated over a flame to the burner until the mixture will turn dark brown. After cooling, 0.5 ml of water was added, followed by 10% sodium hydroxide until basic (blueness on litmus paper), after which the volume of the solution was adjusted to 20 ml with water. The resulting solution should have an intense orange color with green fluorescence.
