GC-MS analysis and in-vitro hypocholesterolemic, anti-rotavirus, anti-human colon carcinoma activities of the crude extract of a Japanese Ganoderma spp

Background and objective Medicinal mushrooms are mines of various biologically active compounds. Therefore, chemical analysis and in-vitro evaluation of some biological activities of the Japanese originated mushroom Ganoderma spp. were conducted. Materials and methods Extraction of the fruiting bodies of Ganoderma spp. was accomplished using 80% methanol. This extract was investigated for its in-vitro cholesterol-lowering activity, anti-rotavirus effect, and anti-human colon cancer influence. Moreover, a gas chromatography-mass spectrometry analysis for this extract was performed. Results and conclusion The gas chromatography-mass spectrometry analysis resulted in the detection of 39 compounds, which were generally saturated and unsaturated fatty acids, and alkenes. The crude extract exhibited a promising in-vitro cholesterol-lowering activity (100±0%) after 96 h of incubation at room temperature. The same crude extract showed a moderate anti-rotavirus SA-11 strain effect with a therapeutic index of 9.3. Moreover, Ganoderma spp. extract displayed a strong activity toward HCT116 human colon carcinoma cell line, resulting in a cytotoxicity of 84.03±0.93% on HCT116 cell line monolayers. Ganoderma spp. crude extract represents a promising source of biologically active compounds that could by further investigations represent support and/or alternative to the currently used drugs.
