Two new compounds from fermentation liquid of the marine fungus Trichoderma atroviride G20-12.

The chemical constituent research on the ethyl acetate extracts of fermentation liquid of the marine fungus Trichoderma atroviride G20-12 led to the isolation of two new compounds, 2-hydroxybutan-3-yl 5'-(2''-hydroxy-N-(2'''-oxobutan-3'''-yl)propanamido)butanoate (1) and 3-hydroxy-5-(4-hydroxybenzyl)dihydrofuran-2(3H)-one (2). The structures of the new compounds were determined by spectroscopic and chemical analysis.
