摘要
探索了橘皮苷分子结构。开展了橘皮苷分子结构中红外(MIR)光谱组学(包括:一维MIR光谱、导数MIR光谱及退卷积MIR光谱)实验。结果发现,橘皮苷分子结构的红外吸收模式包括:橘皮苷分子芳基C-H官能团伸缩振动模式(νC-H_(橘皮苷-退卷积))、橘皮苷分子CH_(3)官能团不对称伸缩振动模式(ν_(αsCH_(3)-橘皮苷-退卷积))、橘皮苷分子CH_(2)官能团不对称伸缩振动模式(ν_(αsCH_(2)-橘皮苷-退卷积))、橘皮苷分子CH_(3)官能团对称伸缩振动模式(ν_(sCH_(3)-橘皮苷-退卷积))、橘皮苷分子CH_(2)官能团对称伸缩振动模式(ν_(sCH_(2)-橘皮苷-退卷积))、橘皮苷分子C=O官能团伸缩振动模式(ν_(sCH_(3)-橘皮苷-退卷积))、橘皮苷分子芳基C=C官能团伸缩振动模式(ν_(sCH_(2)-橘皮苷-退卷积))、橘皮苷分子CH_(2)官能团弯曲振动模式(δ_(C=O_(-橘皮苷-退卷积)))、橘皮苷分子CH_(3)官能团不对称弯曲振动模式(δ_(C=C_(-橘皮苷-退卷积))、橘皮苷分子CH_(3)官能团对称弯曲振动模式(δ_(sCH_(3)-橘皮苷-退卷积))和橘皮苷分子CH_(2)官能团面内摇摆振动模式(ρ_(sCH_(2)-橘皮苷-退卷积))。橘皮苷分子结构退卷积MIR光谱的谱图分辨能力要优于一维MIR光谱及导数MIR光谱。MIR光谱组学可以快速开展橘皮苷分子结构研究。
The molecular structure of hesperidin was explored.The infrared(MIR)spectroscopy experiments(including one-dimensional MIR spectroscopy,derivative MIR spectroscopy,and deconvolution MIR spectroscopy)on the molecular structure of hesperidin were conducted.The results showed that the infrared absorption modes of the molecular structure of hesperidin include:the stretching vibration mode of the aromatic C-H functional group of hesperidin molecule(ν_(C-H_(hesperidin-deconvolution))),the asymmetric stretching vibration mode of the CH_(3)functional group of hesperidin molecule(ν_(αsCH_(3)-hesperidin-deconvolution),the asymmetric stretching vibration mode of the CH_(2)functional group of hesperidin molecule(ν_(αsCH_(2)-hesperidin-deconvolution),the symmetric stretching vibration mode of the CH_(3)functional group of hesperidin molecule((ν_(sCH_(3)-hesperidin-deconvolution)),the symmetric stretching vibration mode of the CH_(2)functional group of hesperidin molecule(ν_(sCH_(2)-hesperidin-deconvolution)),hesperidin molecule C=O functional group stretching vibration mode(ν_(C=O_(-hesperidin-deconvolution))),hesperidin molecule aryl C=C functional group stretching vibration mode(ν_(C=O-hesperidin-deconvolution)),hesperidin molecule CH_(2)functional group bending vibration mode(δ_(CH_(2-hesperidin-deconvolution)),asymmetric bending vibration mode of CH_(3)functional group of hesperidin molecule(δ_(sCH_(3)-hesperidin-deconvolution))),symmetric bending vibration mode of CH_(3)functional group of hesperidin molecule(δ_(sCH_(3)-hesperidin-deconvolution))),and in-plane rocking vibration mode of CH_(2)functional group of hesperidin molecule(ρ_(CH_(2--hesperidin-deconvolution))).The spectral resolution of deconvoluted MIR spectra of hesperidin molecular structure is superior to one-dimensional MIR spectra and derivative MIR spectra.MIR spectroscopy can quickly conduct molecular structure research on hesperidin.
