The Health Promoting Effects of the Fruiting Bodies Extract of the peppery milk cap mushroom Lactarius piperatus (Agaricomycetes) from Serbia
2020
Antioxidant, antimicrobial, genoprotective, anticancer, and neuroprotective potential of acetone extract of the fruiting bodies of the edible mushroom Lactarius piperatus was studied. The antioxidant activity was evaluated using different methods (DPPH radical scavenging, superoxide anion radicals scavenging, reducing power assay, and determination of total phenolic compounds). The microdilution method was used to reveal the antimicrobial potential. The genoprotective potential was determined by Comet assay. Cytotoxic activity was tested using MTT. The capacity of the extract to inhibit acetylcholinesterase was used for determining its neuroprotective potential. The received results show that L. piperatus extract possessed potent health enhancing effects. In the antioxidant activity, IC50 was 33.97 μg/mL for DPPH radicals scavenging and 22.52 μg/mL for superoxide anion radicals scavenging, whereas the absorbance for the reducing power was from 0.0510 to 0.1451. The total content of phenolic compounds in the extract was 5.08 μg PE/mg. The testing of the antimicrobial activity showed that MIC values were from 0.039 to 10 mg/mL. For Comet assay, all concentrations of extract increased the GDI values from 0.46 ± 0.05 to 0.99 ± 0.31. L. piperatus extract expressed relatively strong cytotoxic activity with IC50 values ranging from 37.83 to 65.94 μg/mL. Finally, the percentage of inhibition of acetylcholinesterase activity of tested extract was within the range 16.75-44.35%. Our results imply that the acetone extract of L. piperatus has rather strong antioxidant, antimicrobial, genoprotective, anticancer, and neuroprotective effects; thus this mushroom represents healthy food that could be used in the pharmaceutical industry and to prevent various diseases.
