摘 要 目的:建立新疆紫草的高效液相色谱(HPLC)指纹图谱,进行化学模式识别分析,并测定其中3种成分的含量。方法:采
用HPLC法。以乙酰紫草素为参照,绘制34批不同来源新疆紫草药材样品的HPLC指纹图谱,采用《中药色谱指纹图谱相似度评
价系统(2012A 版)》进行相似度评价,确定共有峰;采用SPSS 19.0、SIMCA 14.1统计软件进行聚类分析、主成分分析和正交偏最小
二乘法-判别分析,以变量投影重要性值大于1为标准,筛选影响新疆紫草药材质量的差异标志物,并以相同HPLC法测定其中3
种成分的含量。结果:34批新疆紫草药材共有12个共有峰;除市售样品中的3批药材相似度低于0.72外,其余药材的相似度均高
于 0.86;共指认出左旋紫草素、乙酰紫草素、β,β′-二甲基丙烯酰阿卡宁等 3 个共有峰。34 批新疆紫草药材可聚为 2 类,其中 S1、
S4~S6、S13、S15~S20、S22、S26~S34 聚为一类,其余聚为一类。前 3 个主成分因子的方差贡献率分别为 52.834%、18.600%、
8.387%,累积方差贡献率为79.821%。左旋紫草素、乙酰紫草素、β,β′-二甲基丙烯酰阿卡宁等 6 个成分为影响其质量的差异标志
物。左旋紫草素、乙酰紫草素、β,β′-二甲基丙烯酰阿卡宁检测质量浓度的线性范围分别为0.72~90、2.05~410、2.50~500 µg/mL
(r 均大于 0.999);定量限分别为 0.132、0.135、0.118 µg/mL,检测限分别为 0.040、0.041、0.036 µg/mL;精密度、稳定性(24 h)、重复
性、耐用性试验的RSD均小于3%;加样回收率分别为95.959%~100.201%(RSD=1.669%,n=6)、97.818%~102.698%(RSD=
1.788% ,n=6)、95.831% ~99.344%(RSD=1.600% ,n=6)。 含 量 分 别 为 0.002% ~0.134% 、0.025% ~1.388% 、0.022% ~
0.881%。结论:所建HPLC指纹图谱和含量测定方法简便、稳定性好,可用于新疆紫草药材的质量评价和定量分析;左旋紫草素、
乙酰紫草素、β,β′-二甲基丙烯酰阿卡宁等成分的含量各有不同,为不同来源新疆紫草的差异标志物。

ABSTRACT OBJECTIVE:To establish the HPLC fingerprint of Arnebia euchroma,analyze them with chemical pattern
recognition technology, and determine the contents of 3 components. METHODS: HPLC method was adopted. Using
acetylshikonin as reference,HPLC fingerprint of 34 batches of A. euchroma from different sources were drawn. Similarity
Evaluation System for TCM Chromatographic Fingerprint(2012A edition)was used to evaluate the similarity of the samples,and
common peaks were determined. SPSS 19.0 and SIMCA 14.1 statistical software was used for cluster analysis,principle component
analysis and orthogonal partial least squares-discriminate analysis. According to the standard of the variable importance in the
project greater than 1,the differential markers affecting the quality difference of A. euchroma were screened. Meanwhile,the
contents of 3 components were determined by the same HPLC method. RESULTS:There were 12 common peaks in HPLC
fingerprints for 34 batches of A. euchroma. The similarity of
