TITLE: Quality evaluation of Lufu pill based on fingerprint chromatography and multi-component content determination
摘要: 目的 评价颅复丸(LFP)的质量。方法采用《中药指纹图谱相似度评价系统(2012版)》建立LFP的高效液相色谱(HPLC)指纹图谱并进行相似度评价;采用SIMCA14.1软件进行层次聚类分析(HCA)、主成分分析(PCA)和正交偏最小二乘-判别分析(OPLS-DA)。采用HPLC法测定12批样品中士的宁、马钱子碱、甘草苷、三七皂苷R1、人参皂苷Rg1、人参皂苷Rb1、甘草皂苷G2、人参皂苷Rd的含量。结果从12批LFP样品的HPLC指纹图谱中标定出26个共有峰,指认出其中8个,分别为士的宁(峰3)、马钱子碱(峰4)、甘草苷(峰6)、三七皂苷R(1峰7)、人参皂苷Rg(1峰8)、人参皂苷Rb(1峰15)、甘草皂苷G(2峰17)、人参皂苷Rd(峰18);12批LFP样品的相似度均大于0.90。HCA和PCA结果均显示,12批样品分为两类,S2、S4~S6、S12为一类,S1、S3、S7~S11为一类;Hotelling’sT2和DModX的控制上限分别为16.631和1.578。人参皂苷Rg(1峰8)、人参皂苷Rb(1峰15)、峰20、士的宁(峰3)、峰11、三七皂苷R(1峰7)、峰2、峰17、峰13、峰10、人参皂苷Rd(峰18)、峰23、峰26、峰21、峰24的变量重要性投影值均大于1。含量测定结果显示,士的宁、马钱子碱、甘草苷、三七皂苷R1、人参皂苷Rg1、人参皂苷Rb1、甘草皂苷G2、人参皂苷Rd的含量分别为0.005%~0.018%、0.005%~0.010%、0.050%~0.118%、0.033%~0.073%、0.132%~0.248%、0.122%~0.242%、0.021%~0.043%、0.016%~0.048%。结论所建HPLC指纹图谱和含量测定方法的准确性、重复性均较好,可用于LFP的质量评价;人参皂苷Rg1、人参皂苷Rb1、士的宁、三七皂苷R1、人参皂苷Rd可能是影响制剂整体质量的差异性成分。
ABSTRACT: OBJECTIVE To evaluate the quality of Lufu Pill (LFP).METHODS The high-performance liquid chromatography (HPLC) fingerprint of LFP was established using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine (2012 Edition), and similarity evaluation was performed. Hierarchical cluster analysis (HCA), principal component analysis (PCA), and orthogonal partial least squares-discriminant analysis (OPLS-DA) were performed using SIMCA 14.1 software. The contents of strychnine, brucine, liquiritin, notoginsenoside R 1 , ginsenoside Rg 1 , ginsenoside Rb 1 , licoricesaponin G 2 , and ginsenoside Rd in 12 batches of samples were determined by the HPLC method.RESULTS A total of 26 common peaks were identified in the HPLC fingerprint of 12 batches of LFP samples, and eight common peaks were identified as strychnine (peak 3), brucine (peak 4), liquiritin (peak 6), notoginsenoside R 1 (peak 7), ginsenoside Rg 1 (peak 8), ginsenoside Rb 1 (peak 15), licoricesaponin G 2 (peak 17), and ginsenoside Rd (peak 18). The similarities of 12 batches of LFP samples were all greater than 0.90. The results of HCA and PCA both showed that the 12 batches of samples were divided into two categories: S2, S4-S6, and S12 were grouped into one category, while S1, S3, S7-S11 were grouped into another category. The upper control limits for Hotelling’s T 2 and DMod X were 16.631 and 1.578, respectively. The variable importance in projection values of ginsenoside Rg 1 (peak 8), ginsenoside Rb 1 (peak 15), peak 20, strychnine (peak 3), peak 11, notoginsenoside R 1 (peak 7), peak 2, peak 17, peak 13, peak 10, ginsenoside Rd (peak 18), peak 23, peak 26, peak 21, and peak 24 were greater than 1.The content determination results showed that strychnine, brucine, liquiritin, notoginsenoside R 1 , ginsenoside Rg 1 , ginsenoside Rb 1 , licoricesaponin G 2 , and ginsenoside Rd were 0.005%-0.018%, 0.005%-0.010%, 0.050%-0.118%, 0.033%-0.073%, 0.132%-0.248%, 0.122%-0.242%, 0.021%-0.043%, and 0.016%-0.048%, respectively.CONCLUSIONS The established HPLC fingerprint and content determination method are accurate and reproducible, and can be used for the quality evaluation of LFP. Ginsenoside Rg 1 , ginsenoside Rb 1 , strychnine, notoginsenoside R 1 , and ginsenoside Rd may be the differential components affecting its overall quality.
