Amanita cokeri (a Poisonous Suspect Mushroom) Contains Chemical Compounds of Industrial Importance

Globally, little research effort is devoted to investigating the potential benefits of toxic or poisonous suspect mushrooms. In this study, we profiled Amanita cokeri metabolites using GC-MS to identify com¬pounds of industrial value. The mushroom was collected at a forest reserve in Ilesa, Southwest Nigeria, and identified by comparing it with literature. Extraction of the metabolite from A. cokeri was done using methanol and characterized using GC-MS. Compound identification was achieved using the NIST 11 mass spectral library. Morphologically, the mushroom was identified as A. cokeri. GC-MS profile revealed that A. cokeri metabolite contained 20 fractions belonging to three functional groups namely, terpene, fatty acid, and its derivatives and sterol. Cis-9-hexadecenal was the most abundant compound (45.07%). 1-(+)-Ascor¬bic acid 2,6-dihexadecanoate and D-limonene were noted for the first time in the mushroom. This study provided background information into the chemical composition of A. cokeri metabolite for possible explo¬ration and exploitation for humankind.
