Study on the structure and identification of salvia miltiorrhiza and radix dipsaci by mid infrared spectroscopy group
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.
