Owing to the complexity of the composition of herbal and dietary supplements, it is a challenging problem to efficiently screen and identify active or toxic compounds. Psoralea corylifolia L. (PCL) was selected as the subbject to establish a methodology for rapid screening and identification of hepatotoxic compounds. High‐content imaging, ultra‐performance liquid chromatography and high‐resolution mass spectrometry were used in this study to detect the hepatotoxicity and identify unknown compounds in PCL samples. Then, putative toxic compounds which are highly related to hepatotoxicity were screened by spectrum–toxicity correlation analysis, and the toxicity intensity verified by high‐content imaging. The maximum nontoxic dose of processed samples with good detoxification effect reduced more than 9 times compared with unprocessed raw medicinal materials. Spectrum–toxicity correlation analysis showed that bavachinin A, bavachin, isobavachalcone and neobavaisoflavone had high correlation with the hepatotoxicity of PCL, and psoralen and isopsoralen had low correlation with hepatotoxicity. This study verified the hepatotoxicity of these six putative compound monomers, proving the results of spectrum–toxicity correlation analysis. Based on the correlation analysis of high‐resolution mass spectrometry of detection compounds and high‐content imaging of hepatocyte toxicity data, the potential toxic compound of herbal and dietary supplement products can be quickly and accurately screened.
