依据薄层色谱斑点上的Rf值、斑点颜色、大小以及整个色谱的指纹分析,对不同产地、不同采收期、不同品级和不同品种的鼠尾草属植物进行鉴别;通过数码摄影实现了对丹参药材水溶性物质群和脂溶性物质群薄层色谱指纹特征的提取与表达。提出将以往数值分类法的研究成果用于中药材物质群指纹特征的表达,用信息量来量化指纹图谱的特征信息,可得出中药材真伪、优劣的判据。

Danshen of different species,from different geographical origins,at different harvest time 'and in different grades of quality have been identified in accordance of the Rf value,color and demension of the spots on their thin -layer chromatography and with the fingerprinting analysis of the entire chromatography,and the acquirement and expression of fingerprinting characteristics of watersoluble and liposoluble masses on the thin-layer chromatography of Danshen have been achieved by digital photography.It is suggested to apply the method of numerical classif cation to the expression of the fingerprinting characteristics of the masses of Chinese medicinal materials and to quantize the characterized information of fingerprints by the amount of information to judge true or false and good or bad Chinese medicinal materials.
