OBJECTIVE To address the shortcomings of the current standard in the Chinese Pharmacopoeia, which only detects two components of Sarcandrae Herba, and establish a multi index component analysis method to analyze the chemical characteristics of medicinal materials from different origins and the transfer patterns of substances in formulations. METHODS UPLC-Q-Exactive Orbitrap-MS/MS was used to identify 41 components in Sarcandrae Herba and its preparations based on retention time, precise mass number (error ≤5×10-6), and fragment ion characteristics, including organic acids (chlorogenic acid, rosmarinic acid), coumarins (isoxazidine), flavonoids (quercetin glucuronide), and terpenes (atractylodes macrocephala Ⅲ). For quantitative analysis, UPLC-QQQ-MS/MS method was established, using acetonitrile 0.1% formic acid gradient elution and negative ion MRM mode to determine the content of 13 components in 20 batches of samples from eight production areas (chromatographic column: Waters CORTECS T3, flow rate 0.3 mL·min-1). For chemical pattern recognition, CA, PCA, and OPLS-DA were combined to analyze differences in origin and screen for quality markers. RESULTS The linear relationship of 13 components was good (r2≥0.997 8), and the precision (RSD≤3.83%), repeatability (RSD≤3.56%), and recovery rate (95%-105%) all met the requirements of the pharmacopoeia. CA divided 20 batches of samples into three categories (Yunnan/Guizhou high rosmarinic acid, Fujian high flavonoids, other balanced types). OPLS-DA identified seven differential biomarkers including quercetin 3-O-β-D-glucuronide (VIP>1, Q2=0.977). The transfer rate of phenolic acids in the formulation is greater than 80%, and terpenoids (such as atractylodes macrocephala Ⅲ) are significantly enriched in alcohol extraction. CONCLUSION For the first time, a multi index quantitative method is established for 13 components of Sarcandrae Herba, covering organic acids, flavonoids, and terpenes. Chemical pattern recognition is used to classify Sarcandrae Herba from different origins. Samples of high rosmarinic acid from Yunnan and high flavonoids from Fujian can be used as a basis for harvesting high-quality medicinal materials. The analysis of terpenoid components provides a new direction for the development of anti-inflammatory topical preparations (such as medicinal wine).
