摘要(Abstract):

[Objective] To compare the chemical constituents from four different cultivars of Amomum villosum in order to provide references for the research on its varieties identification and breeding. [Method] The characteristics of infrared spectra from four different cultivars of Amomum villosum were compared and analyzed by conventional Fourier transform infrared (FTIR) spectroscopy combined with fourth derivative spectrum. [Result] Four cultivars of Amomum villosum samples showed similar infrared absorption in the two bands of 750-1 800 cm-1and 2 700-3 500 cm-1,and their infrared absorption spectra had no significant difference by the fourth derivative spectrum changes in comparison. [Conclusion] Four cultivars of Amomum villosum have no significant difference in the types of chemical constituents, but have subtle differences in content, which show that the germplasm doesnt have a qualitative change.
