采用MIR光谱（包括一维MIR光谱、二阶导数MIR光谱、四阶导数MIR光谱及去卷积MIR光谱）开展了防己结构的研究。试验发现，防己结构的红外吸收模式主要包括ν■、ν■、ν■、ν■、ν■、ν■、δ■、δ■、δ■和ν■。研究发现，防己结构的去卷积MIR光谱的谱图分辨能力要优于相应的一维MIR光谱、二阶导数MIR光谱和四阶导数MIR光谱。本项研究拓展了MIR光谱技术在重要的传统中药（防己）结构的研究范围。

The radix stephaniae tetrandrae structure was studied by MIR spectroscopy (including one-dimensional MIR spectroscopy, second-order derivative MIR spectroscopy, fourth-order derivative MIR spectroscopy and deconvolution MIR spectroscopy). The experiment found that the infrared absorption modes of radix stephaniae tetrandrae structure mainly included: νasCH3-radix stephaniae tetrandrae, νasCH2-radix stephaniae tetrandrae, νsCH3-radix stephaniae tetrandrae, νsCH2-radix stephaniae tetrandrae, νC=O-radix stephaniae tetrandrae, νC=C-radix stephaniae tetrandrae, δ■, δasCH3-radix stephaniae tetrandrae, δsCH3-radix stephaniae tetrandrae and νC-O-radix stephaniae tetrandrae. It was found that the deconvolution MIR spectra of radix stephaniae tetrandrae molecules had better spectral resolution than the corresponding one-dimensional MIR spectra, second-order derivative MIR spectra and fourth-order derivative MIR spectra. This study expanded the research scope of MIR spectroscopy in the molecular structure of important traditional chinese medicine (radix stephaniae tetrandrae).
