Zusammenfassung: | The invention belongs to the field of analytical chemistry, and particularly relates to an analysis method for measuring degradation products of an oral solution containing methylparaben by an HPLC technology. Octadecylsilane chemically bonded silica is selected as a filler, and a mixed solvent of an organic phase and a buffer solution is used as a mobile phase for gradient elution. Degradation impurities are p-hydroxybenzoic acid and p-benzoquinone, the methyl hydroxybenzoate and degradation products thereof in the oral solution containing the methyl hydroxybenzoate can be rapidly separated by adopting the method, the detection method is high in specificity, high in precision and high in accuracy, a solvent does not interfere with determination in detection, and a detection result is reliable and accurate. And the method has extremely important significance for realizing quality control of the oral solution containing methylparaben.
