Isolation and Identification of Secondary Metabolites Produced by Phytopathogenic Fungus from .

The secondary metabolites of the phytopathogenic fungus CC01 from were investigated. As a result, two new compounds, 5-acetyl-7-hydroxy-6- methoxybenzofuran-2(3)-one () and ()-2-(2,3-dihydrofuro [3,2-]pyridin-2-yl)propan-2-ol (), together with seven known compounds, 4,6,8-trihydroxy-3,4-dihydronaphthalen-1(2)-one (), 3,6,8-trihydroxy-3,4-dihydronaphthalen-1(2)-one (), curvulin acid (), 2-methyl-5-carboxymethyl- 7-hydroxychromone (), tyrosol (), -hydroxybenzoic acid () and cerevisterol (), were isolated from the fermentation extract by comprehensive silica gel, reverse phase silica gel, Sephadex-LH20 column chromatography and high-performance liquid chromatography (HPLC). The structures of these compounds were identified by using high-resolution electrospray mass spectrometry (HRESIMS), nuclear magnetic resonance spectroscopy (NMR), optical rotation, ultraviolet and infrared spectroscopy techniques and a comparison of NMR data with those reported in the literature. Compounds and were new compounds, and compounds - were discovered from this phytopathogenic fungus for the first time. Compounds - were tested for phytotoxicity against the fresh tender leaf of , and the results show that none of them were phytotoxic. Additionally, these compounds were subjected to an antimicrobial assay against three bacteria (, and ), but they showed no activity.
