A Systematic Review on Bioactivity of Brazilian Mushrooms (Agaricomycetes).

Metadata-grounded summary

Citation abstract

The medicinal properties of Agaricomycetes mushrooms have been explored for millennia. Several biological activities produced by mushrooms have been evaluated worldwide. Therefore, this systematic review aims to present the studies that evaluated the biological activities demonstrated by mushrooms from Brazil. To select the articles, PubMed, Scopus, ScienceDirect and Google Scholar databases were used, with publications between the years 2001-2018, using the key words "mushrooms," "medicinal properties," "extracts," and "Brazil." The articles were selected according to three inclusion criteria: made with mushrooms from Brazil; title and summary with assessment of biological activity of basidioma or mycelium extracts; title and summary with evaluation of biological activity of isolated compound. Exclusion criteria were: work not done in Brazil; review articles; duplication of articles and abstracts and full texts irrelevant to the topics in question. A total of 31 articles were selected. According to the way used to assess biological activities, 54.8% evaluated from basidioma extract, 32.3% from isolated compound and 12.9% from mycelium extract. A total of 12 biological activities were evaluated, the most frequent were antioxidant (22%), anti-inflammatory (12.2%), anticancer (9.8%), antimicrobial (9.8%), and cytotoxic (7.3%). A total of 22 species of Agaricomycetes were evaluated in the studies, Agaricus blazei (=A. brasiliensis) the most studied (35.5%), mainly for antigenotoxic and anticlastogenic/antimutagenic activities. The most common isolated compounds of Agaricomycetes evaluated were β-glucan, fucogalactane, mannogalactoglucan, amaurocin, and polysaccharides. Agaricomycetes studied in Brazil are promising for medicinal applications.
