目的 建立基于"谱-效-代"关联的参枝苓口服液(SZL)质量标志物(Q-marker)研究策略。方法 测定12批次SZL的HPLC指纹图谱和乙酰胆碱酯酶(AchE)抑制活性,采用正交信号校正-偏最小二乘回归(OSC-PLSR)分析方法建立HPLC指纹图谱和AchE抑制作用之间的谱效关系,结合网络药理学,确定药效相关成分;通过血清药物化学鉴定入血成分,确定药效活性成分;关联整合药效相关成分和药效活性成分,综合分析,挖掘Q-marker。结果 OSC-PLSR分析结果确定了3个药效相关成分与AchE抑制作用密切相关;网络药理学映射与阿尔茨海默病(AD)相关的疾病靶点确定了61个药效相关成分;通过UHPLC-Q Exactive高分辨液质联用技术鉴定了血浆中11个药效活性成分;关联整合综合分析初步确定SZL的Q-marker为芹糖甘草苷、芍药内酯苷和壬二酸。结论 谱效关系、网络药理学和入血成分鉴定的结合是一种快速分析及发现SZL Q-marker的有效方法,对于完善中药质量控制和评价方法,保证中药的安全和有效具有重要意义。

Objective To establish a research strategy for discovering quality marker (Q-marker) of Shenzhiling Oral Liquid based on the "fingerprint-efficacy-pharmacokinetics" correlation. Methods HPLC fingerprints and acetylcholinesterase (AchE) inhibitory activities of 12 batches of Shenzhiling Oral Liquid were analyzed. The correlation analysis between the HPLC fingerprints and AchE inhibitory effects were carried out with orthogonal signal correction-partial least squares regression (OSC-PLSR) method. Combined with network pharmacology, efficacy-related components were determined. By identifying the compounds absorbed and exposed in vivo, pharmacologically active components were determined. Finally, Q-marker could be preliminarily discovered by the comprehensive analysis associated with the integration of efficacy-related components and pharmacologically active ingredients. Results The results of OSC-PLSR analysis showed that three efficacy-related components were closely related to AchE inhibitory activities. According to mapping the targets of diseases, 61 efficacy-related components were determined. Eleven active compounds in plasma were identified by UHPLC-quadrupole-orbitrap-MS. The Q-markers of Shenzhiling Oral Liquid were liquiritin apioside, albiflorin and azelaic acid preliminarily determined by integrated and comprehensive analysis. Conclusion The combination of fingerprint-efficacy relationship, network pharmacology and components absorbed in plasma could be an effective way for rapid analysis and discovery of Q-marker in Shenzhiling Oral Liquid, which will be of great significance both to improve the quality control and evaluation, and ensure the safety and effectiveness of traditional Chinese medicines.
