摘要: 目的 建立超高效液相色谱(UPLC)指纹图谱结合化学计量学方法,评价不同厂家生产的雷公藤多苷片质量。方法 采用Waters Cortecs T3色谱柱(2.1 mm×100 mm,1.6μm);乙腈-水系统为流动相,梯度洗脱;流速0.4 mL·min-1;检测波长220 nm。采用ChemPattern软件建立指纹图谱共有模式,并进行相似度评价、主成分分析和聚类分析。同时采用超高压液相色谱-飞行时间质谱(UPLC-QTOF-MS)技术对共有峰进行鉴定。结果 建立了9个厂家共25批雷公藤多苷片的UPLC指纹图谱,标识51个共有峰,鉴定了其中23个色谱峰的结构,发现多数为生物碱类成分。25批样品的相似度为0.18~0.99,存在不同厂家制剂成分差异较大、部分厂家批次间质量不稳定的问题。主成分分析和聚类分析将9个厂家制剂分为3类,并筛选出3个主要差异性成分。结论 UPLC指纹图谱能够反映不同厂家雷公藤多苷片的成分差异,结合化学计量学方法,可为雷公藤多苷片的质量评价提供参考。

Abstract: Objective To establish UPLC fingerprints of tripterygium glycoside tablets, and to evaluate the quality of preparations from different manufacturers by chemometrics. Methods Chromatographic separation was performed on the Waters Cortecs T3 column (2.1 mm × 100 mm, 1.6 μm). Acetonitrile-water was adopted as the mobile phase for gradient elution. The flow rate was 0.4 mL/min and the detection wavelength 220 nm. ChemPattern software was used for the establishment of the common pattern of fingerprints, similarity evaluation, and for principal component analysis and cluster analysis. At the same time, the common peaks were identified using the UPLC-QTOF-MS method. Results The UPLC fingerprints of 25 batches of tripterygium glycoside tablets from 9 manufacturers were established, and 51 common peaks were determined. Among them, 23 were identified, and most of them were found to be alkaloids. The similarity of the tested samples ranged from 0.18 to 0.99, suggesting that the quality of the samples from different manufacturers and even that of samples of different batches from the same manufacturer varied greatly. Principal component analysis and cluster analysis divided the nine manufacturers’ preparations into three categories and screened out three main different components. Conclusion UPLC fingerprints can reflect the variations in tripterygium glycoside tablets from various manufacturers, which can provide reference for quality evaluation of the preparations based on chemometrics.
