Background : Agaricus bisporus mushroom, which originated from Europe, is an edible mushroom with a unique taste and flavor and is the most widely cultivated mushroom type worldwide, particularly because of the relatively high protein, dietary fiber, and vitamin D contents of the fruit body, which have human health benefits like anticancer and DNA damage protection. However, to our knowledge, few studies have been conducted on the ability to discriminate mushroom’s bioactive compounds according to regional production sites. Thus, this study was aimed to examine the regional difference of selected bioactive compounds in of Agaricus bisporus mushroom.
Methods and Results : The cultivars (cv.) “Saedo” and “Saehan” obtained from five regions of Korea were measured their phenolics and fatty acids profiling by LC/MS and GC-FID system, respectively. Among 54 targeted phenolics, protocatechuic, p-hydroxybenzoic, caffeic, 2,4-dihydrobenzoic, p-coumaric, and salicylic acids were found in the cv. Saedo and cv. Saehan fruit body. Also, tyrosine and phenylalanine, which are precursor metabolites of phemolics, were also observed in the A. bisporus fruit body. In particular, phenylalanine and p-hydroxybenzoic acid were the most abundant phenolic precusor and metabolite present in the A. bisporus, and was significant with the production regions (p < 0.05). The FA content was significant with the production region, but not much differed (p < 0.05). The n-6 FA including linoleic acid was the major FA in the mushroom, accounting > 70% over total FA content. However, the n-3 FA was the n-6 FA was very minor FA metabolites.
Conclusion : These preliminary results can extend knowledge of regional difference of certain targeted bioactive compounds in A. bisporus mushroom produced in Korea, contributing to reliable regional difference with potential broader applications for the international mushroom market.
