- 中文摘要: Ganoderma products could be classified into 3 types according to their raw materials, i.e. fruit bodies, cultured mycelia and the mixtures of both. Seven commercial samples and three mycelia products prepared in laboratory were analyzed by Fourier Transform(FT)-IR spectrophotometer. The fruit-body products gave a weak absorption band at 890~894 cm-1 and the mycelia show a weak to medium band at 774~778 cm-1 on the FT-IR spectra, respectively. These two bands were observed in the IR spectra of mixed-type products. A modified sample pretreatment procedure for the reverse-phase HPLC analysis was also investigated. The spectral patterns revealed that fruit bodies of the commercial samples were the species of G. tsugae.
