摘要
探索了丹参及其续断结构及鉴别.分别开展了丹参及续断结构的中红外(MIR)光谱组学(包括:一维MIR光谱及退卷积MIR光谱)研究.实验发现,丹参及续断结构的退卷积MIR光谱的谱图分辨能力要优于相应的一维MIR光谱.丹参及续断结构的退卷积MIR光谱的主要红外吸收模式包括:vasCH3-退卷积、vasCH2-退卷积、vsCH3-退卷积、vsCH2-退卷积、vC=O-退卷积vamide-Ⅰ-退卷积、vC=C-退卷积、vamide-Ⅱ-退卷积、δCH2-退卷积、δasCH3-退卷积及vC-O-退卷积,其中vasCH3-退卷积、vC=O-退卷积、vamide-Ⅰ-退卷积、vC=C-退卷积、vamide-Ⅱ-退卷积、δCH2-退卷积、δasCH3-退卷积及vC-O-退卷积对应的吸收频率均存在着较大的差异性.MIR光谱组学可以快速开展丹参及续断结构及鉴别研究.
Abstract
The structure and identification of salvia miltiorrhiza and radix dipsaci were explored.Mid infrared(MIR)spectroscopy group(including one-dimensional MIR spectroscopy and deconvolution MIR spectroscopy)of salvia miltiorrhiza and radix dipsaci structure were conducted separately.The experiment found that the spectral resolution of deconvolution MIR spectra of salvia miltiorrhiza and radix dipsaci structure is superior to the corresponding one-dimensional MIR spectra.The main infrared absorption modes of the deconvolution MIR spectra of salvia miltiorrhiza and radix dipsaci structure include:vasCH3-deconvolution,vasCH2-deconvolution,vsCH3-deconvolution,vsCH2-deconvolution,vC=O-deconvolution,vamide-Ⅰ-deconvolution,vC=C-deconvolution,vamide-Ⅱdeconvolution,δCH2-deconvolution,δasCH3-deconvolution and vC-O-deconvolution.There are significant differences in the absorption frequencies corresponding to vasCH3-deconvolution,vC=O-deconvolution,vamide-Ⅰ-deconvolution,vC=C-deconvolution,vamide-Ⅱ-deconvolution,δCH2-deconvolttion,δasCH3-deconvolution and vC-O-deconvolution.MIR spectroscopy can quickly carry out structural and identification studies on salvia miltiorrhiza and radix dipsaci.
