    摘要:
    目的：快速鑒定兩種原植物形態(tài)和化學成分都非常相似的中藥材假東風草和東風草，并研究二者的化學成分差異。 方法：利用UPLC-Q-Exactive-MS/MS分析和鑒定假東風草和東風草中的化學成分，進一步通過化學模式識別分析（CPR）比較和鑒別兩種中藥材，并確定其潛在的標志性成分。同時，建立了一種HPLC方法評價兩種中藥材的質(zhì)量。 結(jié)果：從兩種藥材中共鑒定了93種成分，其中包括54種酚酸類成分，35種黃酮類成分，2種糖類成分，1種酚酸苷和1種其他成分，其中67種是在假東風草和東風草中首次鑒定。化學模式識別分析結(jié)果表明，根據(jù)LC-MS數(shù)據(jù)，可以明顯區(qū)分假東風草和東風草。利用HPLC法得到的峰面積，計算異綠原酸A與隱綠原酸的峰面積比值可以區(qū)分假東風草和東風草，并對其藥材質(zhì)量進行控制。 結(jié)論：假東風草和東風草在化學成分方面存在顯著差異。本實驗為比較和評價假東風草和東風草的質(zhì)量提供了一種快速、便捷的方法。

    Abstract:
    Objective: To rapidly identify the two morphologies and chemical properties of similar herbal medicines, Blumea riparia and B. megacephala as the basis for chemical constituent analysis. Methods: UPLC-Q-Exactive-MS/MS was utilized for profiling and identification of the constituents in B. riparia and B. megacephala. Chemical pattern recognition (CPR) was further used to compare and distinguish the two herbs and to identify their potential characteristic markers. Then, an HPLC method was established for quality evaluation. Results: A total of 93 constituents are identified, including 54 phenolic acids, 35 flavonoids, two saccharides, one phenolic acid glycoside, and one other constituent, of which 67 were identified in B. riparia and B. megacephala for the first time. CPR indicates that B. riparia and B. megacephala samples can be distinguished from each other based on the LC–MS data. The isochlorogenic acid A to cryptochlorogenic acid peak area ratio calculated from the HPLC chromatograms was proposed as a differentiation index for distinguishing and quality control of B. riparia and B. megacephala. Conclusion: This study demonstrates significant differences between B. riparia and B. megacephala in terms of chemical composition. The results provide a rapid and simple strategy for the comparison and evaluation of the quality of B. riparia and B. megacephala.
