黄花地丁结构研究

Study on the structure of dandelion

建立了黄花地丁结构的研究方法。采用中红外(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)开展了黄花地丁结构研究。结果表明,黄花地丁结构的红外吸收模式主要包括,ν_(C-H_(-黄花地丁))、ν_(asCH_(3-黄花地丁))、ν_(asCH_(2-黄花地丁))、ν_(sCH_(3-黄花地丁))、ν_(sCH_(2-黄花地丁))、ν_(C=O-黄花地丁)、ν_(amideⅠ-黄花地丁)、ν_(amideⅡ_(-黄花地丁))、δ_(CH_(2-黄花地丁))、δ_(asCH_(3-黄花地丁))、δ_(sCH_(3-黄花地丁))和ν_(C-O_(-黄花地丁))。黄花地丁结构的去卷积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。黄花地丁的化学成分主要包括芳基结构与油脂结构。

A method for studying the structure of dandelion was established.Middle infrared(MIR)spectra(including one-dimensional MIR spectra,second-order derivative MIR spectra,fourth-order derivative MIR spectra and deconvolution MIR spectra)were used to study the structure of dandelion.The test found that the infrared absorption mode of the structure of the dandelion mainly included:ν_(C-H-dandelion),ν_(asCH3-dandelion),ν_(asCH2-dandelion),ν_(sCH3-dandelion),ν_(sCH2-dandelion),ν_(C=O-dandelion),ν_(C=C-dandelion,νAmideI-dandelion),ν_(AmideII-dandelion),δ_(CH2-dandelion),δ_(asCH3-dandelion),δ_(sCH3-dandelion) andν_(C-O-dandelion).It was found that the deconvolution MIR spectrum of the dandelion structure was superior to the corresponding one-dimensional MIR spectrum,second-order derivative MIR spectrum and fourth-order derivative MIR spectrum.The main chemical constituents of dandelion included aryl structure and oil structure.
