Agaritine content of 53 Agaricus species collected from nature
Original language description
Fifty-three different species of the genus Agaricus were collected in the Czech Republic during the period 1998-2001 and identified by an experienced mycologist. The samples were analysed for agaritine (N2-(gamma-L-glutamyl)-4-hydroxymethylphenylhydrazine) content, a precursor to a suspected rodent carcinogen. There was a huge variation in agaritine content between species, but less variation between samples of a species. Whereas the cultivated mushroom Agaricus bisporus commonly contain 200-500 mg agaritine kg(-1) fresh weight, no less than 24 of the 53 species contained agaritine levels above 1000 mg kg(-1) fresh weight. The highest level was found in A. elvensis containing up to 10,000 mg kg(-1) fresh weight. Twenty species contained intermediate levels (100-1000 mg kg(-1)), and nine species were below 100 mg kg(-1). Some of the species producing low levels of agaritine might be candidates for future strain development of Agaricus mushrooms for cultivation. No correlation could be o
