OBJECTIVE To establish the HPLC fingerprints and content determination method of five index components of Dashanzha pills(DSZP), and evaluate the quality combined with chemical pattern recognition. METHODS The analysis was performed on an Eclipse plus C₁₈ column (4.6 mm×250 mm, 5 μm) at 30 ℃. Acetonitrile-0.1% formic acid aqueous solution was used as the mobile phase for gradient elution at flow rate of 1.0 mL·min^-1. The detection wavelength was set at 250 nm, and the injection volume was 10 μL. Based on 51 batches of DSZP samples, the fingerprint was established, and five index components were identified and quantitatively determined.Cluster analysis, principal component analysis and orthogonal partial least squares discriminant analysis were used to comprehensively analyze 51 batches of samples. RESULTS The fingerprints of DSZP were established, sixteen peaks were identified, and five chemical components were identified. They were chlorogenic acid (peak 5), vanillic acid (peak 6), hyperoside (peak 7), isochlorogenic acid B (peak 9), and isochlorogenic acid A (peak 10).The linear relationship of the five index components was good (r>0.998), and the recovery rate was 96.27%-109.35%, and the RSD was 2.83%-4.07%. The contents of chlorogenic acid, vanillicacid, hyperoside, isochlorogenic acid B, and isochlorogenic acid A were 0.047 2-0.227 0, 0.009 7-0.036 2, 0.023 0-0.370 2, 0.006 4-0.063 2 and 0.021 7-0.064 5 mg·g^-1, respectively. Except for manufacturer Q2, the contents of the products from the other manufacturers samples were maintained at (100±30)% of their respective average values, and the contents of the five components of manufacturer Q2 were mostly higher than 30% of the average value of all samples, indicating that there were great differences in product quality among different enterprises. The results of chemical pattern recognition showed that all samples could be roughly divided into two categories, indicating that the preparation process was relatively stable within the enterprise, but there were some differences between enterprises. The difference markers of the screened samples included the target components chlorogenic acid, hyperoside, and isochlorogenic acid B. CONCLUSION The quantitative method is accurate, rapid and feasible. Combined with chemical pattern recognition method, it can be used to evaluate the quality of DSZP.

作为我国中医药经典名方,大山楂丸(Dashanzha pills,DSZP)由山楂、六神曲(麸炒)、炒麦芽3味药细粉与炼蜜、水等混合而成的大蜜丸,具有消食化滞、调和脾胃的作用^[1]。“性味”是中药的特有属性,反映了中药的本质特征,是中药药性理论的核心。DSZP味酸,酸味能收能涩,该类药物的物质基础多以有机酸类为主。DSZP与复方消化酶对于肠胃消化功能的恢复均有促进作用,且相比于复方消化酶,DSZP具有价优质廉,安全性高的特点^[2]。山楂作为君药,又富含黄酮类成分,具有多种现代药理作用^[3-4]。在《中国药典》2020年版基础上,目前DSZP的质量控制多以单个成分的含量测定为主,且时间较久远^[5-6],缺乏系统性控制。当前药典中对DSZP的检测项目主要有性状、鉴别、检查、含量测定,从近年来国家药品评价抽检情况来看,中成药质量状况易受生产投料原料质量状、工艺等的影响,导致部分中成药出现一些质量问题^[7-9]。DSZP的安全性较好,受众人群广,需求量大,生产企业多,不同厂家、不同批次间的质量是否存在差异及整体质量如何尚无文献报道。故本文结合前期研究基础,基于中成药整体质量控制的理念,建立DSZP的指纹图谱,并对绿原酸、香草酸、金丝桃苷、异绿原酸B、异绿原酸A等5种指标性成分进行含量测定,借助化学模式识别方法对多批次DSZP进行全面质量特征分析,旨在为其质量控制提供参考。

2.1 溶液的制备

2.1.1 对照品溶液的制备

精密称取绿原酸、香草酸、金丝桃苷、异绿原酸B、异绿原酸A等对照品适量,分别于10 mL量瓶中,甲醇溶解并定容,制得绿原酸、香草酸、金丝桃苷、异绿原酸B、异绿原酸A质量浓度为1.025 1、1.074 7、0.918 6、1.010 4、0.973 1 mg·mL^-1的单一对照品溶液。精密吸取上述单一对照品溶液各适量,甲醇定容5 mL量瓶,得到绿原酸、香草酸、金丝桃苷、异绿原酸B、异绿原酸A质量浓度分别为82.000 0、10.747 0、36.744 0、16.166 4、27.246 8 μg·mL^-1的混合对照品溶液,于4 ℃ 条件下保存,备用。

2.1.2 供试品溶液制备

取样品适量,剪碎,称取2 g,与硅藻土等比例混合后研成粉末。精密称定粉末2 g(精确至0.001 g),置于150 mL锥形瓶中,精密量取甲醇溶液25 mL,称量,加热回流提取1 h,静置放冷后再次称重,用甲醇溶液补足,离心(8 000 r·min^-1,5 min)后取出上清液,60 ℃减压浓缩,浓缩液转移至5 mL量瓶,甲醇少量多次冲洗,洗涤液一并转移至量瓶,甲醇定容至刻度,摇匀后0.45 μm有机微孔滤膜过滤,取续滤液即得。

2.1.3 阴性样品溶液制备

DSZP由山楂、麸炒六神曲、炒麦芽等3味药组方而成,《中国药典》2020年版收载DSZP项下制法为3种粉末直接与炼蜜等混合制成,故在阴性试验中与供试品溶液制备方法保持一致,分别制得山楂、麸炒六神曲、炒麦芽的单一样品溶液。

2.2 色谱条件

采用Agilent公司Eclipse Plus C₁₈色谱柱(4.6 mm×250 mm,5 μm);流动相:乙腈-0.1%甲酸水溶液,梯度洗脱:0~5 min,5%~6%乙腈;5~12 min,6%~12%乙腈;12~20 min,12%~15%乙腈;20~26 min,15%~19%乙腈;26~40 min,19%~33%乙腈;40~55 min,33%~55%乙腈;55~60 min,55%~75%乙腈;60~65 min,75%~90%乙腈;65~70 min,90%~5%乙腈70~72 min,5%乙腈;流速:1.0 mL·min^-1,检测波长:250 nm,柱温:30 ℃,进样量:10 μL。

2.3 指纹图谱研究

2.3.1 精密度试验

取DSZP(编号H4),按“2.1.2”项下方法进行供试品溶液的制备,按“2.2”项下色谱条件连续进样6次,以5号峰(绿原酸)为参照峰,测得各共有峰相对保留时间及相对峰面积的相对标准偏差(RSD)值,均小于3.0%,表明仪器精密度良好。

2.3.2 重复性试验

取DSZP(编号H4)平行6份,精密称定,按“2.1.2”项下方法制备供试品溶液,在“2.2”项下色谱条件进样测定,记录各色谱图。以5号峰(绿原酸)为参照峰,测得各共有峰相对保留时间及相对峰面积的RSD值,均小于3.0%,表明该方法重复性好。

2.3.3 稳定性试验

取DSZP(编号H4),按“2.1.2”项下方法制备供试品溶液,在“2.2”项色谱条件下,分别于0、2、4、8、12、24 h测定,记录各色谱图。以5号峰(绿原酸)为参照峰,测得各共有峰相对保留时间及相对峰面积的RSD值,均小于3.0%,表明供试品溶液于24 h内测定结果稳定。

2.3.4 对照指纹图谱的建立及相似度评价

取11个厂家产DSZP 51批样品,按“2.1.2”项下方法进行供试品溶液的制备,按“2.2”项下色谱条件采集色谱数据,对各色谱图进行积分后,导出AIA格式的文件,分别将其导入《中药色谱指纹图谱相似度评价系统(2012.130723 版本)》进行处理,将其他样品的色谱峰与参照图谱进行自动匹配,生成DSZP叠加图谱及对照图谱,见图1。设定H4为参照图谱,时间窗宽度设定为0.2 min,采用中位数法,进行全谱峰匹配,生成DSZP对照指纹图谱。共标定出16个共有峰,其中5号峰(绿原酸)稳定性好,色谱响应高,保留时间适中,故选择该色谱峰为参照峰(S),计算得51批DSZP指纹图谱相似度。结果表明,Q1~Q11 11个厂家生产DSZP的相似度分别为:0.919~1.000、0.829~0.958、0.920~0.980、0.653~0.676、0.872~0.982、0.866~0.889、0.709~0.839、0.713~0.740、0.641~0.647、0.633~0.636、0.657~0.671。

2.3.5 色谱峰归属及指认

精密吸取“2.1”项下各溶液,按“2.2”项下色谱条件进样分析,与指纹图谱共有峰进行对比。结果16个共有峰中的13个色谱峰分属于山楂、麸炒六神曲及炒麦芽,其余3个保留时间分别为7.97 min(2号峰)、34.71 min(11号峰)、58.24 min(13号峰)的色谱峰未能归属。

经与对照品比较指认了5个色谱峰,分别为绿原酸(5号峰)、香草酸(6号峰)、金丝桃苷(7号峰)、异绿原酸B(9号峰)、异绿原酸A(10号峰),见图2。

2.4 含量测定研究

2.4.1 专属性考察

取“2.1”项下3种溶液,在“2.2”色谱条件下进样,记录色谱图,目标成分均达到基线分离,可见供试品呈现与对照品保留时间一致的色谱峰。在阴性样品色谱图中,绿原酸、香草酸在3味药材中均可检测到,除此之外,山楂中可测到金丝桃苷和异绿原酸B,麸炒六神曲中可测到异绿原酸A和异绿原酸B,麦芽中可测到异绿原酸A,且炒麦芽和麸炒六神曲中整体色谱峰的响应值较低,具体见图3。

2.4.2 线性关系

分别吸取“2.1.1”项下混合对照品溶液0.1、0.2、0.4、0.8、1.2、1.6 mL,分别置于2 mL量瓶中,用甲醇定容至刻度,摇匀,配制成梯度浓度的混合对照品溶液,按照“2.2”项下色谱条件测定。以对照品溶液质量浓度(X,μg·mL^-1)为横坐标,峰面积(Y)为纵坐标进行标准曲线绘制,见表2。

2.4.3 方法学考察

按“2.1.2”项下方法制备供试品溶液,依“2.2”项下色谱条件,连续进样6次,结果绿原酸、香草酸、金丝桃苷、异绿原酸B、异绿原酸A峰面积的RSD均<3%,表明仪器精密度良好。精密称取样品(编号:H4),按“2.1.2”项下方法平行制备6份溶液,按“2.2”项下色谱条件分别进样测定,绿原酸、香草酸、金丝桃苷、异绿原酸B、异绿原酸A的平均含量分别为0.163 0、0.019 7、0.116 3、0.018 6、0.035 7 mg·g^-1,RSD均<3%,结果表明,该方法重复性良好。精密称取样品(编号:H4),按“2.1.2”项下方法制备供试品溶液,按“2.2”项下色谱条件,分别于0、2、4、8、12、24 h测定,结果绿原酸、香草酸、金丝桃苷、异绿原酸B、异绿原酸A峰面积的RSD均<3%,结果表明,该方法在24 h内稳定性良好。

2.4.4 加样回收率试验

精密称取样品(编号:H4)0.5 g,平行6份,分别按1:1加入对照品溶液,在“2.1.2”项下方法制备供试品溶液,进样分析,计算回收率,结果绿原酸、香草酸、金丝桃苷、异绿原酸B、异绿原酸A平均加样回收率(n=6)分别为98.09%、107.15%、109.35%、96.27%、105.27%,RSD值均小于4.5%,结果见表3。

2.4.5 样品测定

对51 批大山楂丸按“2.1.2”项下方法制备供试品溶液,平行3份,在“2.2”项色谱条件进样分析,见表4。结果显示,所有样品中绿原酸的均值为0.133 0 mg·g^-1,香草酸均值为0.021 1 mg·g^-1,金丝桃苷均值为0.118 4 mg·g^-1,异绿原酸B均值为0.023 3 mg·g^-1,异绿原酸A均值为0.041 0 mg·g^-1,多个企业的目标化合物明显超出所有样品均值±30%,表明企业间的产品质量存在较大差异,单一投料药材对DSZP整体质量的影响有待进一步的深入研究;Q2企业中所有目标成分含量均不同程度超出所有样品均值±30%,为进一步突出含量差异,利用Origin 21制作含量雷达图,见图4。

3 化学模式识别研究

收起

3.1 聚类分析

对51批样品进行共有峰指认,得到16个共有峰,以绿原酸为参照峰,得到共有峰的相对保留时间,见表5。以此共有峰峰面积为原始数据,用SPSS 25进行聚类分析,具体见图5。可知,当组间距离为20时,所有样品可分为两类,Q1、Q3~Q13聚为一类,Q2单独聚为一类。表明被区分后的两类样品各自相似性较大,Q2与其余厂家样品的差异性显著。

3.2 主成分分析(PCA)

以51批样品的16个共有峰峰面积为变量进行最基本的降维分析(PCA), 导入 SPSS 25.0 软件,以特征值>1 为提取标准^[10],得到4个主成分因子,累积方差贡献率达到 75.709%,从一定程度上可为样本的质量评价提供参考依据。主成分及方差贡献率见表6。将共有成分峰面积导入 SIMCA 14.1 软件,经分析生成得分图,见图6,该结果与聚类分析结果基本一致。

3.3 正交偏最小二乘判别分析(OPLS-DA)

为进一步验证主成分分析结果的准确性,再次将共有成分峰面积导入SIMCA 14.1建立OPLS-DA模型,自动拟合后R²X、R²Y分别为0.940和0.603,预测能力参数Q²为0.536,OPLS-DA得分图见图7,同主成分分析结果一致。为防止过拟合现象出现,随后进行200次的置换检验,见图8,说明该模型稳定性较强,预测能力较好。变量重要性投影 (variable importance for the projection,VIP)是筛选不同样品间差异性化合物的重要指标,VIP 值越大,对差异的影响越大。经分析后得到16个共有成分的VIP值,结果见图9。以VIP值大于1为标准,得到8个变量,其中5号峰是绿原酸,7号峰是金丝桃苷,9号峰是异绿原酸B,即导致样品差异性的主要标志物。

4.1 供试品溶液的制备方法考察

本研究对供试品溶液的提取方法(超声、回流)、提取时间(30 min、1 h)、提取溶剂为甲醇(体积分数30%、50%、70%、100%)、体积分数95%乙醇,提取体积(10、25、50 mL)进行了系统考察。综合考虑样品的提取率、整体色谱行为、色谱峰信息的丰富情况、主要色谱峰的峰形、分离度及峰面积,环境的友好性。最终确定,当2 g样品中加入25 mL的甲醇,加热回流提取1 h为最佳提取条件。

4.2 指纹图谱及含量测定化学模式识别结果

本实验首次建立了11个生产厂家51批 DSZP的指纹图谱,能够较全面地对市售DSZP 的质量状况进行评估。整体样本指纹图谱的相似度介于0.633~1.000,其中Q1、Q3两厂家产品相似度均大于0.9,接近1.0;Q2、Q5、Q6三个厂家产品相似度均大于0.8,接近0.9;Q4、Q9、Q10、Q11四个厂家产品相似度均在0.65左右,由此提示,同一厂家产品间一致性较好,不同厂家产品间存在较大差异。基于指纹图谱的构建,可以弥补中成药质量控制指标与临床关系不紧密、“碎片化”的现象。探索中成药产品质量一致性的评价策略^[11-12],保障临床用药的安全、有效,意义重大。DSZP中指标性成分定量测定结果表明,同一厂家产DSZP中指标性成分的含量基本保持在各自均值的±30%,说明不同企业内部不同批号样品的均一性较好,生产工艺环境稳定可靠。在此基础上,厂家Q2的5种指标性成分含量显著高于所有样品均值的±30%,加之16个共有峰峰面积整体偏大,表明Q2厂家DSZP的整体质量要优于其余厂家样品,也表明不同企业间的产品质量存在较大差异,初步推测受投料原料质量状况影响较大。通过化学模式识别的方法进行更进一步的数据挖掘,聚类分析表明,当欧式距离为15时,所有样品大致可分为3类,当欧式距离为20时,样品可被聚为两类,其中Q2始终被单独聚为一类。由主成分分析得分图可知,该分析结果与聚类结果保持一致,OPLS-DA中筛选得到8个影响样品间差异性原因的变量因子,其中包含定量分析的绿原酸、金丝桃苷和异绿原酸B。这3个目标成分主要存在于山楂中,大山楂丸中规定山楂以生品入药,但不排除某些企业用其他炮制品代替,Luo等^[13]研究山楂炒焦前后DSZP化学成分进行分析,发现生品与焦品存在部分共有成分,其中包含绿原酸。因此,企业在生产前应严格把控投料药材的质量。

5 分析与总结

收起

《中国药典》2020年版收载DSZP【鉴别】项下,对山楂、炒麦芽的部分显微特征进行了描述;通过盐酸-镁粉反应对黄酮类化合物进行了鉴别;利用TLC法对熊果酸进行鉴别。【含量测定】项下,采用薄层扫描法,建立了熊果酸的含量测定方法,仅对投料山楂的质量进行控制。由此可见,对于DSZP的质量控制手段较为单一,未能有效对投料进行全面的控制,难以反映其整体内在质量。同时,处方中六神曲的制法收载于《卫生部药品标准·中药成方制剂》^[14]《全国中药炮制规范》^[15],但全国各省地方标准亦多有收载^[16-19],受发酵环境、终点确定等的影响,致使六神曲的品质良莠不齐,这可能是导致DSZP质量差异的重要原因,值得进一步关注。中成药通常由多味中药组方而成,物质组成复杂、多样,是其发挥药效的关键,同时也是全面的质量控制的难点。指纹图谱技术可以整体地展示被测样品的化学特征全貌,是最适合中成药整体质量控制的技术之一^[20],结合多指标成分定量测定,运用化学模式识别对测定数据进行深度挖掘表征,可进一步提升质量控制水平。

本试验建立了一种DSZP中HPLC法同时测定多成分含量方法,并结合化学计量学统计分析方法对51批样品整体进行质量评价。该方法结果可靠,准确性高,能够反映出市售DSZP的质量情况,可为山楂丸的质量标准提升提供参考。
