| Abstract: | In this paper, the vibrational spectra of Gastrodia elata Blume and one of it's fakes were studied by Fourier Transform Infrared Spectroscopy (FTIR). The results show that Gastrodia elata Blume and one of its confusable varieties -potatoes have characteristic infrared spectrum respectively, and the remarkable differences are in the region between 1240 and 1500 cm~(-1), by which Gastrodia elata Blume can be identified from its confusable varieties. Wild growing and cultivated Gastrodia elata Blume can be discriminated by FTIR according to the differences of their spectra peaks and absorbance ratios. FTIR is proved to be a rapid and non-destructive method in identification of Gastrodia elata Blume. |
