摘 要 目的:建立壮瑶药三妹木的高效液相色谱(HPLC)指纹图谱,为不同产地三妹木的质量评价提供依据。方法:以广西南
宁、桂林、梧州等5不同产地的10批三妹木为样品,采用“中药色谱指纹图谱相似度评价系统”(2012版)软件建立HPLC指纹图谱
并进行相似度评价[色谱柱为Inertsil ODS-3,流动相为乙腈-0.2%磷酸溶液(梯度洗脱),流速为0.8 mL/min,检测波长为350 nm,柱
温为35 ℃,进样量为10 μL],通过对照品比对对共有峰进行指认。采用IBM SPSS 21.0软件对其进行聚类分析和主成分分析。结
果:建立了HPLC指纹图谱,共确定了12个共有峰,并指认了其中3个共有峰(8、10、11号共有峰分别为夏佛塔苷、牡荆素和异牡荆
素);10批样品的相似度均大于0.9。经聚类分析发现,10批药材可聚为二大类;经主成分分析发现,2个主成分因子的累计方差贡
献率为 86.108%(第一主成分、第二主成分的贡献率分别为 66.891%、19.217%)。结论:成功建立了三妹木药材的 HPLC 指纹图
谱,该方法简单、易行,为三妹木的质量控制提供了可靠的评价方法。

ABSTRACT OBJECTIVE:To establish HPLC fingerprint of Zhuang and Yao medicine Lespedeza formosa,and to provide
reference for quality control of L. formosa from different producing areas. METHODS:Totally 10 batches of samples were
collected from 5 producing areas as Guangxi Nanning,Guilin,Wuzhou and so on. HPLC fingerprints was established and
similarity analysis was carried out by using“Similarity evaluation system of TCM chromatographic fingerprint”(2012 edition)
software. The determination was performed on Inertsil ODS-3 column with mobile phase consisted of acetonitrile-0.2% phosphoric
acid solution(gradient elution)at the flow rate of 0.8 mL/min. The detection wavelength was set at 350 nm,and the column
temperature was 35 ℃ . The sample size was 10 μ L. Common peaks were identified by comparing substance control. Cluster
analysis and principal compoent analysis were performed by using IBM SPSS 21.0 statistical software. RESULTS: HPLC
fingerprint was established,and 12 common peaks were calibrated. 3 common peaks were identified(common peak 8,10,11
were chafotalin,vitexin and isovitexin). The similarity of 10 batches of samples were all higher than 0.9. Through cluster analysis,
10 batches of medicinal materials could be clutered into 2 groups. According to the principal component analysis,the cumulative
variance contribution rate of the two principal component factors was 86.108%(contribution rates of first principal components and
second principal components were 66.891% and 19.217%). CONCLUSIONS:HPLC fingerprint of L. formosa is established
successfully. The method is simple and easy to use,provides a reliable evalution method for quality control of L. formosa.
