Identification of Peels Among Three Strains of in Changqing by Multi-steps Infrared IR Macro-fingerprint Method
Objective: To study the peels among three strains of Trichosanthes kirilowii in changqing by IR spectra method. Method: The general infrared spectroscopy (FTIR)
secondary derivative spectroscopy and two dimensional correlation infrared spectroscopy (2D-IR) were used to analyze the powder of the three strains of T. kirilowii. Result: In the one-dimensional spectra and the secondary derivative
the three strains of T. kirilowii. had certain differences in shape
position and intensity of partial absorption peaksin 2D-IR spectra the three strains had obvious feature. Conclusion: The multi-steps infrared IR macro-fingerprint is a rapid and accurate method to identify three strains of T. kirilowii.
