目的 基于指纹图谱及网络药理学，开展质控成分及其功能关联分析的麝香通心滴丸质量一致性评价研究。 方法 采用超高效液相色谱-四极杆飞行时间质谱（UPLC-Q-TOF-MS/MS）联用法及对照品比对鉴定麝香通心滴 丸的药效成分，并通过超高效液相色谱建立指纹图谱，开展各批样品一致性及差异分析。采用网络药理学方法 探讨麝香通心滴丸的药效成分治疗冠心病的作用机制。结果 鉴定出麝香通心滴丸的组分有原儿茶醛、丹酚酸 B、丹酚酸A、蟾毒它灵、蟾毒灵、酯蟾毒配基、华蟾酥毒基、人参皂苷Re、人参皂苷Rg1、人参皂苷Rd，建 立了超高效液相色谱指纹图谱。聚类分析及主成分分析结果显示，10批样品可聚分为两类，即保质期以内的 S1、S2、S3、S4 四批样品聚分为一类，其余在保质期以外的样品聚为一类，两类样品共有峰含量差异较大。 正交偏最小二乘判别分析结果显示，丹酚酸B、原儿茶醛、蟾毒它灵、蟾毒灵是引起组间差异的主要成分。网 络药理学结果显示，蟾毒它灵、蟾毒灵、华蟾酥毒基、酯蟾毒配基、丹酚酸A、丹酚酸B、人参皂苷Re、人参 皂苷Rg1及人参皂苷Rd为麝香通心滴丸治疗冠心病的重要成分，其作用机制与酪氨酸激酶受体（ErbB）信号通 路、血管内皮生长因子（VEGF）信号通路、叉头框蛋白 O（FoxO）信号通路、磷脂酰肌醇 3-激酶-蛋白激酶 B （PI3K/Akt）信号通路等有关。结论 UPLC-Q-TOF-MS/MS 技术能对麝香通心滴丸进行化学成分分析及质量控 制，可为麝香通心滴丸质量一致性评价及质量监管的重点关注指标选择提供依据。蟾毒它灵、蟾毒灵、华蟾酥 毒基、酯蟾毒配基、丹酚酸A、丹酚酸B、人参皂苷Re、人参皂苷Rg1及人参皂苷Rd为麝香通心滴丸质控及功 效成分，其能通过ErbB、VEGF、FoxO、PI3K/Akt等信号通路发挥治疗冠心病的作用。

Objective To carry out the consistency evaluation study on the efficacy and quality control components of Shexiang Tongxin Dropping Pills based on the correlation analysis of fingerprint and network pharmacology. Methods The ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS） method and a comparison of reference standards were used to identify the pharmacodynamic components of Shexiang Tongxin Dropping Pills. The fingerprint was established by ultra-performance liquid chromatography，then consistency evaluation and differential analysis of each batch of samples were conducted. The network pharmacological method was used to explore the mechanism of action of the pharmacodynamic components of Shexiang Tongxin Dropping Pills in the treatment of coronary heart disease. Results Protocatechualdehyde，salvianolic acid B，salvianolic acid A，bufotalin， bufalin，resibufogenin，cinobufagin，ginsenoside Re，ginsenoside Rg1 and ginsenoside Rd were identified from the components of Shexiang Tongxin Dropping Pills， and ultra-performance liquid chromatography fingerprints were established. The results of cluster analysis and principal component analysis showed that the 10 batches of samples could be grouped into two categories：S1，S2，S3，and S4 samples within the shelf-life period grouped into one category， and the remaining samples outside the shelf-life period grouped into another category. There is a significant difference in the content of common peak between the two categories of samples. The results of orthogonal partial least squares discriminant analysis showed that salvianolic acid B， protocatechinaldehyde， bufotalin and bufalin were the main components that caused the differences between the groups. The results of network pharmacology showed that salvianolic acid B，salvianolic acid A，bufotalin，bufalin，resibufogenin，cinobufagin，ginsenoside Rd，ginsenoside Re and ginsenoside Rg1 were important components of Shexiang Tongxin Dropping Pills in the treatment of coronary heart disease. Their mechanism may be associated with ErbB signaling pathway，VEGF signaling pathway，FoxO signaling pathway and PI3K / Akt signaling pathway. Conclusion UPLC-Q-TOF-MS / MS technology can be used for chemical composition analysis and quality control of Shexiang Tongxin Dropping Pills， which provides a basis for the quality consistency evaluation of Shexiang Tongxin Dropping Pills and the selection of key indicators for quality supervision. Bufotalin， bufalin， resibufogenin， cinobufagin， salvianolic acid A， salvianolic acid B， ginsenoside Re， ginsenoside Rg1 and ginsenoside Rd were the quality control and efficacy components of Shexiang Tongxin Dropping Pills. They can play a role in the treatment of coronary heart disease through ErbB，VEGF，FoxO，PI3K/Akt and other signaling pathways.
