[The application of infrared spectra and clustering analysis in the discrimination of geographical origin of Flos Chrysanthemi].
OBJECTIVE
To identify the origin of Flos Chrysanthemi.


METHODS
FTIR (Fourier transform infrared spectroscopy) and SIMCA (sofe independent modeling of class analogy).


RESULTS
The correctness of every classification was higher than 60%.


CONCLUSIONS
This approach was proved to be a reliable and practicable method for the discrimination of geographical origin of Chrysanthemum.
