title: Comparative study of contents of several bioactive components in fruiting bodies and mycelia of culinary-medicinal mushrooms.
abstract: Mushrooms have been consumed for thousands of years, and several bioactive components were found therein, including lovastatin, γ-aminobutyric acid (GABA) and ergothioneine. The study reported herein was to analyze these three bioactive components in 15 fruiting bodies and 9 mycelia of 19 species of mushrooms from genera Agaricus, Agrocybe, Auricularia, Boletus, Ganoderma, Hypsizygus, Inonotus, Lentinus, Morchella, Pleurotus, Tremella, Termitomyces, and Volvariella. The results show that Hypsizygus marmoreus contained the highest amount of lovastatin (628.05 mg/kg) in fruiting bodies and Morchella esculenta contained the highest amount (1438.42 mg/ kg) in mycelia. Agaricus brasiliensis contained the highest amount of GABA (1844.85 mg/kg) in fruiting bodies, and mycelia of Boletus edulis, Pleurotus citrinopileatus, and Termitomyces albuminosus contained extraordinarily higher amounts (1274.03, 1631.67, and 2560.00 mg/kg, respectively). Volvariella volvacea contained the highest amount of ergothioneine (537.27 mg/kg) in fruiting bodies and mycelia; Boletus edulis, Pleurotus ferulae, and P. salmoneostramineus contained relatively higher amount of ergothioneine too (258.03, 250.23, and 222.08 mg/kg, respectively). However, none of these components was detected in fruiting bodies of Inonotus obliquus. In conclusion, these three bioactive components were commonly found in most mushrooms, and these results might be related to their beneficial effects.
