摘 要:目的建立轻身调脂消渴片(QTXT)的指纹图谱,并进行化学模式识别分析,同时测定7种成分的含量。方法以盐酸黄连碱为参照,采用《中药色谱指纹图谱相似度评价系统(2012版)》建立13批QTXT的高效液相色谱(HPLC)指纹图谱并进行相似度评价;通过与混合对照品色谱图比对,确认共有峰;通过与各单味饮片样品溶液和各阴性样品溶液色谱图比对,确定共有峰的归属;采用SPSS 22.0、SIMCA 14.1软件进行聚类分析、主成分分析和正交偏最小二乘法-判别分析,以变量重要性投影(VIP)值大于1为标准筛选影响QTXT质量的标志性成分。以盐酸黄连碱为内参物,采用一测多评(QAMS)法测定柚皮苷、橙皮苷、新橙皮苷、盐酸小檗碱、盐酸巴马汀和洛伐他汀的含量,并与外标法测定结果(盐酸黄连碱除外)进行比较。结果13批QTXT中共有17个共有峰,相似度为0.987~0.999;共指认出7个共有峰,分别为柚皮苷(4号峰)、橙皮苷(5号峰)、新橙皮苷(6号峰)、盐酸黄连碱(8号峰)、盐酸巴马汀(9号峰)、盐酸小檗碱(10号峰)、洛伐他汀(14号峰)。7~10号峰为黄连的专属峰;3~6、11~13号峰为麸炒枳实的专属峰;14号峰为红曲的专属峰;1号峰为黄连和红曲的共有峰;2、15号峰为麸炒枳实和红曲的共有峰;16、17号峰为6味饮片的共有峰。聚类分析结果显示,13批QTXT可聚为3类,其中S2为一类,S1、S9、S10为一类,S3~S8、S11~S13为一类;主成分分析结果显示,前3个主成分的累计方差贡献率为85.120%,与聚类分析相比,主成分分析进一步将S1与S9、S10区分开;正交偏最小二乘-判别分析结果显示,有7个共有峰的VIP值大于1,依次为10号峰(盐酸小檗碱)、9号峰(盐酸巴马汀)、5号峰(橙皮苷)、11号峰、8号峰(盐酸黄连碱)、12号峰、6号峰(新橙皮苷)。QAMS法测得柚皮苷、橙皮苷、新橙皮苷、盐酸小檗碱、盐酸巴马汀、洛伐他汀的含量分别为40.198~77.552、6.138~13.413、71.OBJECTIVE To establish the fingerprint of Qingshen tiaozhi xiaoke tablets(QTXT)and carry out the analysis of chemical pattern recognition,and determine the contents of seven active components simultaneously.METHODS Using coptisine hydrochloride as reference,the Similarity Evaluation System for Chromatographic Fingerprint of TCM(2012 edition)was utilized to establish the HPLC fingerprints of 13 batches of QTXT and analyze their similarity.The common peaks were confirmed by comparing with the chromatogram of the mixed control;the attribution of the common peak was determined by comparing the chromatograms of the sample solutions of single decoction pieces and negative sample solutions;using SPSS 22.0 and SIMCA 14.1software,cluster analysis(CA),principal component analysis(PCA)and orthogonal partial least squares-discriminant analysis(OPLS-DA)were carried out,and the markers affecting the quality of QTXT were screened,using the variable importance in projection(VIP)value greater than 1 as the standard.Using coptisine hydrochloride as internal reference,the contents of naringin,hesperidin,neohesperidin,berberine hydrochloride,palmatine hydrochloride and lovastatin were determined by quantitative analysis of multicomponents by single marker(QAMS),and then compared with the results(except for coptisine hydrochloride)of external standard method.RESULTS There were 17 common peaks in 13 batches of QTXT,and the similarity was0.987-0.999.Seven chromatographic peaks were identified,namely naringin(peak 4),hesperidin(peak 5),neohesperidin(peak 6),coptisine hydrochloride(peak 8),palmatine hydrochloride(peak 9),berberine hydrochloride(peak 10),lovastatin(peak 14).Peaks 7-10 were the exclusive peaks of Coptis chinensis;peaks 3-6 and 11-13 were the exclusive peaks of bran-fried Fructus aurantii;peak 14 was the exclusive peak of Monascus purpureus;peak 1 was the common peak of C.chinensis and M.purpureus.Peak 2 and 15 were the common peak of bran-fried F.aurantii and M.purpureus;peaks 16 and 17 were the common peaks of 6 tradition
