| TITLE: | Quality evaluation of Qingwen hufei granules based on fingerprints combined with multi-component content determination |
| 摘要: | 目的 为清瘟护肺颗粒质量评价及临床应用提供科学依据。方法以14批清瘟护肺颗粒为样品,采用《中药色谱指纹图谱相似度评价系统(2012版)》建立其高效液相色谱(HPLC)指纹图谱,并进行色谱峰指认和相似度评价。应用聚类分析(CA)、主成分分析(PCA)和正交偏最小二乘-判别分析(OPLS-DA)对14批样品进行化学模式识别分析。同时,采用HPLC法测定样品中新绿原酸(NGA)、绿原酸(CHA)、隐绿原酸(CGA)、连翘酯苷A(FTA)、3,5-O-二咖啡酰奎宁酸(3,5-O-DA)、4,5-O-二咖啡酰奎宁酸(4,5-O-DA)及安格洛苷C(AGC)的含量。结果指纹图谱和含量测定的方法学考察结果均符合相关要求。14批样品的HPLC指纹图谱中共标示出14个共有峰,并指认出其中7个共有峰[NGA(峰2)、CHA(峰3)、CGA(峰5)、FTA(峰11)、3,5-O-DA(峰12)、4,5-O-DA(峰13)和AGC(峰14)];各样品的相似度均大于0.94。CA、PCA结果显示,样品可被分为3类;OPLS-DA结果显示,4号峰(未知)、11号峰(FTA)、8号峰(未知)、9号峰(未知)、1号峰(未知)为差异性成分。14批样品中NGA、CHA、CGA、3,5-O-DA、FTA、4,5-O-DA、AGC的含量范围分别为0.2104~0.4587、0.2691~0.5063、0.2281~0.4611、0.4439~1.0446、0.0667~0.1557、0.0628~0.1438、0.0574~0.1057mg/g。结论本研究建立的HPLC指纹图谱及多成分含量测定方法高效、可靠,可用于清瘟护肺颗粒的质量评价。 |
| ABSTRACT: | OBJECTIVE To provide a scientific basis for the quality evaluation and clinical application of Qingwen hufei granules. METHODS Fourteen batches of Qingwen hufei granules were used as samples to establish high-performance liquid chromatography (HPLC) fingerprints using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine (2012 Edition). The chromatographic peaks were identified and the similarity was evaluated. Cluster analysis (CA), principal component analysis (PCA), and orthogonal partial least squares-discriminant analysis (OPLS-DA) were used to conduct chemical pattern recognition analysis on the 14 batches of samples. Meanwhile, the contents of neochlorogenic acid (NGA), chlorogenic acid (CHA), cryptochlorogenic acid (CGA), forsythoside A (FTA), 3,5-O-dicaffeoylquinic acid (3,5-O- DA), 4,5-O-dicaffeoylquinic acid (4,5-O-DA), and angoroside C (AGC) in the samples were determined by HPLC. RESULTS The methodological investigation results of both the fingerprint and the content determination complied with the relevant requirements. Fourteen common peaks were indicated in the HPLC fingerprints of the 14 batches of samples, and 7 of them were identified [NGA (peak 2), CHA (peak 3), CGA (peak 5), FTA (peak 11), 3,5-O-DA (peak 12), 4,5-O-DA (peak 13), and AGC (peak 14)]; the similarity of each sample was greater than 0.94. The results of CA and PCA showed that the samples could be classified into 3 categories; the results of OPLS-DA indicated that peak 4 (unknown), peak 11 (FTA), peak 8 (unknown), peak 9 (unknown), and peak 1 (unknown) were the differential components. The content ranges of NGA, CHA, CGA, 3,5-O-DA, FTA, 4,5-O-DA and AGC in the 14 batches of samples were 0.210 4-0.458 7, 0.269 1-0.506 3, 0.228 1-0.461 1, 0.443 9-1.044 6, 0.066 7-0.155 7, 0.062 8-0.143 8, and 0.057 4-0.105 7 mg/g, respectively. CONCLUSIONS The HPLC fingerprint and multi-component content determination methods established in this study are efficient and reliable, and can be used for the quality evaluation of Qingwen hufei granules. |
