    Abstract:
    OBJECTIVE: To establish an FTIR method for the analysis of Dendrobium. METHOD: Using fourier transform infrared spectrometer to record the characteristic spectra of eleven samples of Dendrobium, and to compare the spectra by PCA (principal component analysis). RESULT: The FTIR spectra of the upper part of the stem displayed significant differences between fresh and dried samples of Dendrobium. On the other hand, differences were observed in the spectra of the middle and lower parts of stems of D. guangxieuse when compared to other species. CONCLUSION: The method of applying PCA to FTIR analysis is a rapid and dependable method for comparing samples of Dendrobium.
