Bioactive composition of the solid culture of the edible mushroom Pleurotus citrinopileatus on rice and the antioxidant effect evaluation
The edible mushroom Pleurotus citrinopileatus was fermented on cooked rice by the solid-state fermentation technique.The ethyl acetate extract of the P citrinopileatus-fermented rice showed the strong reducing ability in antioxidant bioassay.Indole-3-carboxaldehyde (1),5,7-dimethoxyisobenzofuran-l(3H)-one (2),3,5-dihydroxybenzyl acetate (3),4-hydroxybenzaldehyde (4),4-hydroxybenzaldehyde (5),and ergosterol (6) were isolated from the ethyl acetate extract.Their structures were elucidated on the basis of MS and NMR spectroscopic data.Their antioxidant effects of the DPPH scavenging activity,the chelating ability,and the reducing ability,were screened.The isolation of indole-3-carboxaldehyde as a secondary metabolite from edible mushroom and its structural assignment were reported for the first time.The P.citrinopileatus-fermented rice might be useful as a new functional food.
