摘要	Truffles, which belong to ascomycetes, are rare wild growing edible mushrooms; their fruit body contains high nutritive value composition, and their polysaccharide constituents have potential medical applications. In the present paper, Fourier transform infrared (FTIR) spectroscopy was used for obtaining vibrational spectra of mushrooms of truffles growing in mountains of Yunnan province, southwest China. The results show that the mushrooms exhibit characteristic spectra. The two strongest absorption bands appear at about 1 077 and 1 042 cm(-1), respectively. The spectra exhibit complicated patterns between 1200 and 750 cm(-1), which may be used as fingerprints to discriminate different species of truffles. Great changes were also found between mold and healthy truffles, showing major differences observed in the bands of protein. In addition, some vibrational-spectrum. differences were observed among the same species of truffles from different growing areas. It is showed that FTIR can provide valuable information about the chemical constituents of intact truffles prior to any extraction method is used.
