One new terphenyl glycoside (1), gliocladinin D, together with 4 known compounds (2-5) were isolated from the sponge-derived fungus Trichoderma reesei (HN-2016-018). The structure of the new compound was elucidated by the comprehensive spectroscopic analysis, including 1-dimensional and 2-dimensional nuclear magnetic resonance, and high-resolution electrospray ionization mass spectrometry. Compound 3 exhibited moderate Topo I inhibitory activity.
