Constituents from the Endophytic Fungus of Annulohypoxylon nitens

A chemical study on then-BuOH-soluble fraction of the 95% EtOH extract of rice fermented with the endophytic fungusAnnulohypoxylon nitens has resulted in the isolation of one new natural pyrrole derivative, designated as nitenspyrrole (1), together with 3 known compounds, taraxasterol (2), oleanolic acid (3), andβ-sitostenone (4). Their structures were elucidated by spectroscopic analyses including 1D and 2D NMR experiments, and by ESI-MS.
