It is both challenging and meaningful for identifying the in vivo metabolites of the complex prescription owning to more complex chemical constituents and better therapeutic effect than those of the single medicine. In this paper, a target integration strategy combined with tandem mass spectrometry technology was developed for identification of metabolites from monomer composition of representative standard to Ding-Zhi-Xiao-Wan prescription (DZXW). The representative standards of each type in DZXW were utilized fully to explore the rule of mass fragmentation and the metabolism in vitro. These study were then extended to the single medicine and finally to the DZXW prescription. In addition, the order of metabolic research followed the metabolic order of oral drug in body, namely from in vitro, to intestine tract, to liver, to blood, and ultimately to target organs. As a result, a total of 150 prototypes and 51 metabolites of DZXW were effectively detected and identified in vivo. This result laid a material foundation for the better application of DZXW in treating Alzheimer's disease. More importantly, this analysis strategy provided a deep insight for the drug metabolism of traditional Chinese medicine.
由于复杂的处方比单一药物具有更多的化学成分和更好的治疗效果，因此鉴定其体内代谢物既具有挑战性又具有意义。本文开发了一种目标整合策略，结合串联质谱技术，用于鉴定单体组成的代表标准到定志消丸（DZXW）的代谢物。充分利用 DZXW 中的每种类型的代表性标准来探索质量碎裂和体外代谢的规律。然后将这些研究扩展到单药，最终扩展到 DZXW 处方。此外，代谢研究的顺序遵循药物在体内口服的代谢顺序，即从体外到肠道，再到肝脏，再到血液，最后到靶器官。结果，在体内有效检测和鉴定了 DZXW 的总共 150 个原型和 51 个代谢物。该结果为 DZXW 在治疗阿尔茨海默病中的更好应用奠定了物质基础。更重要的是，这种分析策略为中药的药物代谢提供了深入的见解。
