目的 建立经典名方当归四逆汤(Danggui Sini Decoction,DSD)指纹图谱并结合化学模式识别进行分析,建立多成分含量测定的方法,明确关键质量属性的传递规律。方法 采用HPLC法,乙腈-0.2%乙酸水溶液为流动相,建立指纹图谱,采用中药色谱指纹图谱相似度评价软件(2012年版),结合层次聚类分析(hierarchical cluster analysis,HCA)、主成分分析(principal component analysis,PCA)与正交偏最小二乘法-判别分析(orthogonal partial least squares-discriminant analysis,OPLS-DA),寻找造成不同批次DSD物质基准质量差异的主要化学成分。制备15批物质基准,测定其指纹图谱相似度、指标性成分含量及干膏率。结果 建立了当归四逆汤指纹图谱,确定了16个共有峰,15批DSD物质基准相似度大于0.90,3种化学识别模式均将样品分为3类,造成主要差异的质量差异物来源于甘草苷。所建立的多成分含量测定方法耐用性良好。饮片-物质基准芍药苷、甘草苷、甘草酸的平均转移率分别为52.94%、48.79%、47.39%,干膏率平均传递率为86.40%。结论 建立了经典名方当归四逆汤指纹图谱,寻找出了造成批次差异的标志物及含量测定的方法,DSD物质基准的关键质量属性均可在饮片-水煎液-物质基准中稳定传递,初步构建DSD全过程质量控制体系,为后续制剂研究提供参考。

Objective To establish a fingerprint of the classical formula Danggui Sini Decoction (当归四逆汤, DSD) and combine it with chemical pattern recognition to analyze and establish a method for multi-component content determination, clarify the transmission law of key quality attributes. Methods HPLC was used to establish the fingerprint of DSD, and traditional Chinese medicine (TCM) Chromatographic Fingerprint Similarity Evaluation Software (2012) combined with hierarchical cluster analysis (HCA), principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) were used to evaluate the quality differences between different batches of substance benchmark of DSD, and find the main chemical composition causing quality differences between batches. Fifteen batches of material benchmarks were prepared, and their fingerprint similarity, index component content and dry paste rate range were determined. Result The fingerprint of DSD was established, and 16 common peaks were determined. The similarity of 15 batches of DSD was greater than 0.90. The samples were divided into three categories by three chemical recognition modes, and the quality markers that caused the main difference came from liquiritin. The established method for the determination of multi-component content has good durability. The average transfer rates of paeoniflorin, liquiritin and glycyrrhizic acid were 52.94%, 48.79%, and 47.39%. Respectively, the average transfer rate of dry paste rate was 86.40%. Conclusion To establish an HPLC fingerprint of the substance benchmark of classic prescription DSD and evaluate its quality with chemical pattern recognition method. The markers causing batch differences and the content determination methods of seven components were found. The critical quality attributes of DSD substance benchmarks can be stably transferred from decoction pieces to decoction finally to substance benchmarks, and the whole process quality control system of DSD was preliminarily constructed to provide reference for subsequent preparation research.
