FOURIER TRANSFORM INFRARED AND GAS CHROMATOGRAPHY-MASS SPECTROMETER EXTRACTS FROM EUSCAPHIS JAPONICA BARK

Due to the lack of studies on the chemical constituents of Euscaphis japonica bark, infrared spectroscopy and gas chromatography-mass spectrometer (GC-MS) techniques were used to analyze the ethanol, phenyl alcohol and methanol extracts from Euscaphis japonica bark, laying a foundation for the efficient utilization of Euscaphis japonica bark. Through experimental verification, different extracts of Euscaphis japonica bark can yield different chemical substances: Stigmast-4-en-3-one, (1R,8a alpha)-1,4a beta-dimethyl -7 beta -(1-hydroxy-1-methylethyl)decalin-1 alpha-ol, lactose, Vitamin E, 9,12-octadecadienoic acid, n-hexadecanoic acid, Arsenous acid Tris(trimethylsilyl)ester 4-hydroxy-3-methoxycianamylic alcohol, etc. It was determined that most of the chemicals in Euscaphis japonica bark are soluble in ethanol reagents. According to the relevant mass spectrometry data, Euscaphis japonica bark contains useful pharmaceutical ingredients and chemical raw materials and has broad development prospects.
