摘要:

本研究旨在建立玫瑰花与月季花的高效薄层指纹图谱(HPTLC)分析方法,用于两者的鉴别。该方法采用HPTLC技术选用硅胶G60薄层板,乙酸乙酯-甲酸-水(15∶1∶1)为展开剂,10%硫酸乙醇溶液显色,在366 nm波长下测得薄层色谱图谱,采用指纹图谱系统解决方案软件建立指纹图谱,并进行相似度评价、聚类分析、主成分分析及正交偏最小二乘判别分析。结果显示玫瑰花与月季花样品分别含有9、11个共有峰。玫瑰花种内相似度≥0.987,月季花种内相似度≥0.982,玫瑰花与月季花的相似度为0.520,聚类分析、主成分分析及正交偏最小二乘判别分析均可将玫瑰花与月季花样品区分开,并筛选出11个差异性物质。本研究所建立的方法简便,重现性好,专属性强,可为玫瑰花和月季花的鉴别及质量评价提供参考。

Abstract:

The purpose of this study is to establish HPTLC fingerprint analysis method of Rosa rugosa and R. chinensis for the identification of both.The method adopts HPTLC technology,selects silica gel 60 HPTLC plate was adopted,ethyl acetate∶formic acid∶water (15∶1∶1) as developing agent.Visualization of the chromatogram was performed by spraying with 10% sulphuric acid-ethanol solution.The TLC chromatograms were measured at 366 nm.Fingerprint system solution software was used to establish fingerprint,and similarity evaluation,cluster analysis,principal component analysis and orthogonal partial least squares discriminant analysis were carried out.The results showed that R. rugosa and R. chinensis samples contained 9 and 11 common peaks respectively.The intraspecific similarity of R. rugosa samples ≥ 0.987,and that of R. chinensis≥ 0.982.The similarity between R. rugosa and R. chinensis was 0.520.Cluster analysis,principal component analysis and orthogonal partial least squares discriminant analysis can distinguish R. rugosa from R. chinensis.The 11 differential substances were screened.The method established in this study is simple,reproducible and specific.It can provide a reference for the identification and quality evaluation of R. rugosa and R. chinensis.
