| Zusammenfassung: | The invention discloses a method for determining phthalate content in traditional Chinese medicine by adopting a liquid chromatography-mass spectrometry method, characterized by comprising the following steps: (1) preprocessing a sample to be measured, and (2) determining the content of one kind or multiple kinds of phthalate in the sample after the preprocessing step by adopting the liquid chromatography-mass spectrometry method. The determining method is advantaged by high sensitivity, strong specificity, excellent accuracy degree, and suitability for determining multi-component residues of phthalate in traditional Chinese medicine such as lanceolata, white peony root, red peony root, radix rehmanniae, and the like. |
