Mushrooms do not constitute a significant portion of the human diet, but their consumption continues to increase due to their functional benefits and presence of bioactive compounds. Some of those compounds can be found in the phenolic, polysaccharidic and lipidic fractions of edible and inedible species. Herein, those fractions of five wild mushrooms (Coprinopsis atramentaria, Lactarius bertillonii, Lactarius ...

A comparative study on chemical composition (nutritional value, primary and secondary metabolites), antioxidant properties (scavenging activity, reducing power and inhibition of lipid peroxidation), and antimicrobial activity (antibacterial and demelanizing properties) of two samples of Morchella esculenta (morel) from different countries (Portugal and Serbia) was performed. This species was chosen for being on...

Mushroom extracts or isolated compounds may be useful in the search of new potent antimicrobial agents. Herein, it is described the synthesis of protected (acetylated) glucuronide derivatives of p-hydroxybenzoic and cinnamic acids, two compounds identified in the medicinal mushroom Ganoderma lucidum. Their antimicrobial and demelanizing activities were evaluated and compared to the parent acids and G. lucidum e...

Several edible mushrooms extracts are known to have tumor cell growth inhibitory potential. The objective of this work was to study this potential in extracts of Suillus luteus collected from the Northeast of Portugal. Various extracts were prepared and their effect on tumor cell growth was studied with the SRB assay in four human tumor cell lines: MCF-7 (breast), NCI-H460 (non-small cell lung cancer), AGS (gas...

Heleno, Sandrina A.; Ferreira, Isabel C. F. R.; Ćirić, Ana; Glamočlija, Jasmina; Martins, Anabela; Queiroz, Maria João R. P.; Soković, Marina

Despite the available data regarding antimicrobial activity of phenolic acids, studies dealing with the effects of their metabolites or derivatives are scarce. Therefore, the antimicrobial and demelanizing activities of Coprinopsis atramentaria extract, its organic acids, and methylated and glucuronated derivatives were evaluated. The antifungal activity was stronger than the antibacterial effects. In general, ...
