Study on infrared spectra of Citrus grandis peels from Guangxi Zhuang Autonomous Region.

[Objective] This study aimed to establish the infrared (IR) spectra fingerprints for peels of Citrus grandis from Guangxi Zhuang Autonomous Region. [Method] The fingerprint was established by fourier transform infrared spectroscopy (FT-IR), and then were analyzed by Omic software. [Result] IR spectra fingerprint of C. grandis were successfully established. There were six common peaks in the characteristic spectra of 12 samples. [Conclusion] The specific, rapid and stable method can be applied to quality control of C. grandis.
