The rhizome of Atractylodes chinensis (RAC), also known as “Cangzhu”, is a well-known Chinese herbal medicine (CHMs). Due to the scarcity of wild resources, cultivated RAC and counterfeit products derived from the rhizome of Atractylodes japonica (RAJ) are also prevalent on the market. Diverse origins lead to varying quality. At present, the Chinese Pharmacopoeia (2020 edition) uses atractylodin as the only quantitative index component for RAC, and there is a lack of research on quality markers (Q-markers) that are closely related to efficacy. This work aims to discover the Q-markers of RAC based on chemical and pharmacological strategies. The chemical composition of RAC was analyzed and identified through gas chromatography-mass spectrometry (GC–MS). The ″Chromatographic Fingerprint Similarity Evaluation System for Traditional Chinese Medicine″ was utilized to assess the similarity of the samples and identify the characteristic peaks. Network pharmacology was employed to screen targets and pathways for characteristic components of the RAC, construct “active ingredients–targets–pathways” network diagrams, and predict the Q-markers. The Q-markers for RAC were identified through an integrated analysis of the chemical components, network pharmacology, pharmacological activities and clinical applications. In addition, a preliminary evaluation of 28 batches of “Cangzhu” from different origins were conducted by GC-MS and chemical pattern recognition. A total of 16 specific componen...
