该研究旨在融合超高效液相色谱(UPLC)指纹图谱、多指标成分含量同时测定方法,结合化学模式识别分析,系统探讨不同批次平调颗粒的特性,为其质量评估提供科学依据。采用ACQUITY UPLC BEH Shield RP C
18
色谱柱(150 mm×2.1 mm,1.7 μm),以0.1%磷酸水溶液-乙腈为流动相进行梯度洗脱。共标定了15个共有特征峰,其中7个特征成分经对照品指认,并对天麻素、芍药苷、巴利森苷A、巴利森苷E、松脂醇二葡萄糖苷、槲皮苷6个成分的含量进行测定,17批平调颗粒采用聚类分析(HCA)、主成分分析(PCA)和正交偏最小二乘法-判别分析(OPLS-DA)分类并筛选差异成分。17批样品的相似度均大于0.9;聚类分析和主成分分析的分类结果将17批样品聚为3类,OPLS-DA分析筛选出3个差异性成分;不同批次平调颗粒中上述6个成分的含量差异较小,方法确保了其准确性和可靠性,能够有效地应用于平调颗粒的质量监控与评价。
The study integrated the fingerprinting technique,multi-indicator determination of the content of each component,at the same time,chemical pattern recognition analysis to systematically explore the characteristics of different batches of Pingtiao granules and to provide a scientific basis for their quality assessment. The analytes were separated on an ACQUITY UPLC BEH Shield RP C
18
column(150 mm×2.1 mm,1.7 μm) by gradient elution,with 0.1% aqueous phosphoric acid-acetonitrile as the mobile phase. A total of seven characteristic components were identified,and the contents of six active components,including gastrodin,paeoniflorin,Parishin A,Parishin E,pinoresinol diglucoside and quercetin were determined. Additionally,the 17 batches of Pingtiao granules were classified by cluster analysis(HCA) and principal component analysis (PCA),and then subjected to orthogonal least partial squares-discriminant analysis(OPLS-DA),in order to screen out the different components among the batches of the samples. The UPLC fingerprints of Pingtiao granules and the determination of the contents of 6 index components were established. 15 common peaks were identified and 7 components were designated,and the similarity of the 17 batches was greater than 0.9. The results of HCA and PCA showed that the components of the 17 batches were clustered into 3 categories,and the OPLS-DA analysis screened out 3 markers that caused the differences between batches. The determination of multi-component conte
nt showed that the differences in chemical content between batches were small. The established UPLC fingerprints and the method for determining the content of the six index components ensure their accuracy and reliability. When combined with the chemical pattern recognition technique,this method can be effectively applied to the quality monitoring and evaluation of Pingtiao granules.
