title: A new compound from Stereum insigne CGMCC5.57.
abstract: Studies of the EtOAc extract of the culture broth and methanol extract of the mycelium of Stereum insigne CGMCC5.57 led to the isolation of one new dihydrobenzofuran (1) and six known compounds (2-7). The structures of compounds were elucidated mainly by HRESIMS experiments, and 1D, 2D NMR spectroscopy analysis. This is the first report about the chemical constitutes of the fungus S. insigne.
