FTIR identification between Amomum villosum hybrid offspring and female parent / 中草药

ABSTRACT

Objective: To study the identification between the Amomum villosum hybrid offspring and the female parent by useing the Fourier transform infrared (FTIR) spectroscopy. Methods: Using the FTIR to determine the infrared spectra of A.villosum hybrid offspring and female parent. Switching and processing the atlas with derivative spectrometry and Fourier self-deconvolution, to contrast for the characteristic differences in absorbance of them. Results: There were no significant differences between the A. villosum hybrid offspring and female parent by using FTIR. But 1 051.014 cm-1 was found to be the most obvious in the fourth-derivative spectrum, 771.563 4 and 1 612.432 5 cm -1 to be the most obvious in the Fourier self-deconvolution spectra. Conclusion: There are obvious differences between the A. villosum hybrid offspring and female parent in the derivative spectrometry and Fourier self-deconvolution spectroscopy atlas. Therefore, this method can be used to identify the A.villosum hybrid offspring and female parent simply, rapidly, and accurately.
