Abstract

Two new compounds, 7-hydroxy-5-methoxy-4,6-dimethyl-7-O-α-l-rhamnosyl-phthalide (2) and 7-hydroxy-5-methoxy-4,6-dimethyl-7-O-β-d-glucopyranosyl-phthalide (3), along with one known and related metabolite 7-hydroxy-5-methoxy-4,6-dimethylphthalide (1) were isolated from the EtOAc extract of fermentation broth of an endophytic fungus Pestalotiopsis heterocornis. The structures of these compounds were elucidated on the basis of spectroscopic methods (UV, IR, HR-ESI-MS, 1D NMR, and 2D NMR).
