目的 通过建立UPLC-ESI-IT-TOF/MS分析方法对芪苓温肾消囊方提取物化学成分进行分析,结合文献报道,初步推测可能的起效成分。方法 采用Waters ACQUITY UPLC BEH C₁₈色谱柱(100 mm×2.1 mm,1.7μm);以乙腈-0.1%甲酸水溶液为流动相梯度洗脱;体积流量为0.4 mL/min;ESI源正负离子模式检测。结果 通过对照品比对、质谱数据以及参考文献,共指认出来源于黄芪、淫羊藿、苍术、丹参4味药材共36个化学成分,其中包括19个黄酮类成分、11个酚酸类成分、4个三萜皂苷类成分、1个倍半萜苷类及1个生物碱类成分。结论 对芪苓温肾消囊方提取物的化学成分进行了较为全面的分析,初步阐明了芪苓温肾消囊方的药效物质基础,对于复方中药化学成分物质基础研究及质量控制具有重要意义。

Objective To establish a method for the content identification of chemical constituents in Qiling Wenshen Xiaonang Formula by using UPLC-ESI-IT-TOF/MS, which can infer the potential active ingredients in the formula, combining with literature. Methods The chromatography separation was performed on a Waters ACQUITY UPLC BEH C₁₈ column(100 mm×2.1 mm, 1.7μm) with acetonitrile-0.1% formic acid in water by gradient elution. Electrospray ionization(ESI) source was applied and operated in both positive and negative ion mode. Results A total of 36 chemical constituents were identified by ESI/MS through comparison on chemical standards and literature data, including 19 flavonoids, 11 phenolic acids, four triterpenoid saponins, one sesquiterpene glycoside, and one alkaloid. Conclusion This study introduces a comprehensive analysis method for chemical ingredients in Qiling Wenshen Xiaonang Formula, and lays a foundation for the further analysis on the substance basis research. The results provide a significant guidance for the substance basis research and quality control of compound Chinese materia medica.
