[Analysis and evaluation of different radial parts of Cordyceps kyushuensis by Fourier transform infrared spectroscopy].

Fourier-transform infrared spectroscopy (FTIR) and second derivative spectra were used to analyze and evaluate the different parts of Cordyceps kyushuensis Kob in the present work. The results showed that C. kyushuensis contained proteins, polysaccharides, nucleosides, lipids and other active ingredients, the single-dimensional IR spectra of the various parts were highly similar, the similarity coefficient between the cultured stroma and medium reached up to 0.
