Acetone extract of Flammulina velutipes caps: a promising source of antioxidant and anticancer agents

In this study, the caps of Flammulina velutipes (commonly called Enoki), an edible mushroom, were extracted with different solvents and characterized for in vitro antioxidant and anticancer activities. The anticancer activity of the extract was studied against breast cancer cells (MCF-7 and MDA-MD-231) and normal or Vero breast cells (MCF-10a). The radical scavenging, metal reducing power, and anticancer properties of the extracts were investigated via in vitro chemical and cell-based methods. Furthermore, a phytochemical profiling process was performed on the extract fraction with the highest level of biological activities using Liquid chromatography-mass spectrometry coupled with quadrupole time of flight (LC-MS-QTof). The results showed acetone fraction of Enoki caps to exhibit more radical scavenging activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radicals (IC50 = 0.840 mg/mL) and hydrogen peroxide (H2O2) radicals (IC50 = 0.890 mg/mL) compared to the ethyl acetate fraction (IC50 = 0.97 mg/mL against DPPH and 1.180 mg/mL against H2O2). Additionally, acetone fraction showed a better metal reducing property in a concentration-dependent manner. The in vitro cytotoxicity study showed a preferential level of toxicity of the acetone extract to the studied cancer cell lines compared to the Vero cells. This extract showed more cytotoxicity against MCF-7 (IC50 value ranged from 17.7 µg/mL to 38.36 µg/mL) and MDA-MB-231 (IC50 value ranged from 114.5 µg/mL to 184.2 µg/...
