- Abstract
The study was to establish a method for the simultaneous determination of arsanilic acid, roxarsine, 5-nitroguaiacol sodium, p-nitrophenol sodium, o-nitrophenol sodium, 2-methyl-5-isopropylphenol and 5-methyl-2-isopropylphenol in veterinary drugs by high performance liquid chromatography. 40% methanol solution was used as solvent to pretreat the sample by ultrasonic extraction. The analyses were performed on a C18 column with the gradient elution of mixed salt solution-acetonitrile-methanol. The results showed that the detection limit of seven compounds were in the range of 0.4~1.6 g/kg. The average recoveries were 99.7%~102.9%, with relative standard deviations of 0.2%~1.0%. The study indicates that the proposed method is efficient, reliable and sensitive, which can be used for the simultaneous determination of organic arsenic, nitrophenol and oregano oil in veterinary drugs.
