Abstract
Three new compounds, 4-hydroxyphenethyl-2′-hydroxypropanoate (1), 6-(1′,2′-dimethyloxiran-1′-yl)-4-methoxy-3-methyl-2H-pyran-2-one (2), 6-(1-hydroxyethyl)-4-methoxy-3-methyl-2H-pyran-2-one (3), along with the two known compounds, nectriapyrone (4) and wermopyrone (5), have been isolated from the endophytic fungus of Cephalotaxus hainanensis. Their structures were determined on the basis of chemical and spectroscopic methods.
