Study on the Structure of Raw Cassia Seed and Fried Cassia Seed by Middle Infrared Spectroscopy
The cassia seed structure(including:raw cassia seed and fried cassia seed)was studied by middle infrared(MIR)spectroscopy(including:one-dimensional MIR spectroscopy,second derivative MIR spectroscopy,fourth derivative MIR spectroscopy and deconvolution MIR spectroscopy).The experiment results showed that the infrared absorption modes of cassia seed structure included νasCH3-cassia seed,νasCH2-cassia seed,,νsCH3-cassia seed,as CH3-cassia seed,as CH2-cassia seed,νsCH3-cassia seed,νsCH2-cassia seed,νC=O-cassia seed,νamide-Ⅰ-cassia seed,νamide-Ⅱ-cassia seed and νC-O-cassia seed;and the research found that the spectrum quality of deconvolution infrared spectroscopy was better than one-dimensional MIR spectroscopy,second derivative MIR spectroscopy and fourth derivative MIR spectroscopy.The main components of cassia seed included polysaccharide,protein and oil.The research of this paper expanded the scope of MIR spectroscopy in the study of the structure of important Chinese medicines(raw cassia and stir-fried cassia).
