中医药是在多种特色成分的协同作用下，发挥整体治疗作用的。中医的整体论哲学与代谢组学的整体、系统理论是一致的。所提出的伪靶向代谢组学方法被用于建立可靠的质量控制标记，用于中药的筛选策略。伪靶向代谢组学结合了靶向和非靶向方法的优点。本研究采用靶向代谢组学方法，结合金标准RRLC-QQQ-MS方法，对典型特征成分进行体内定量血浆药物化学研究。同时，使用具有更好的特异性和选择性的UHPLC-QE Orbitrap HRMS的非靶向代谢组学用于鉴定复杂血浆基质中的非靶向代谢物。总共定量测定了32种原型代谢物，其中66种生物转化代谢物与四种标记柑橘类中药的标准提取物一起口服后得到了令人信服的鉴定。系统地描述了复杂中药的整体吸收和代谢过程。
Traditional Chinese medicine (TCM) exerts its therapeutic effect in a holistic fashion with the synergistic function of multiple characteristic constituents. The holism philosophy of TCM is coincident with global and systematic theories of metabolomics. The proposed pseudotargeted metabolomics methodologies were employed for the establishment of reliable quality control markers for use in the screening strategy of TCMs. Pseudotargeted metabolomics integrates the advantages of both targeted and untargeted methods. In the present study, targeted metabolomics equipped with the gold standard RRLC-QqQ-MS method was employed for in vivo quantitative plasma pharmacochemistry study of characteristic prototypic constituents. Meanwhile, untargeted metabolomics using UHPLC-QE Orbitrap HRMS with better specificity and selectivity was employed for identification of untargeted metabolites in the complex plasma matrix. In all, 32 prototypic metabolites were quantitatively determined, and 66 biotransformed metabolites were convincingly identified after being orally administered with standard extracts of four labeled Citrus TCMs. The global absorption and metabolism process of complex TCMs was depicted in a systematic manner.
