GLC--mass spectral analysis of fungal metabolites

Four metabolites, hispidin, bisnoryangonin, muscimole, and ibotenic acid, from potentially psychoactive mushrooms were analyzed by GLC--mass spectrometry as their trimethylsilyl derivatives. This method was applied to the first two compounds in Gymnopilus punctifolius (Peck) Singer and to the last two compounds in Amania pantherina (Fr.) Secr.
